content: 1) Was there an oops moment with this meter? For example, did you have the meter on ohms while trying to measure mains ACV (240V) by accident?2) If you short the probes and set the knob to DCV, does the meter show 0.00 VDC?3) Does the meter show open circuit when set to resistance with the probes not touching anything?4) If you short the probes and set the knob to ohms, does the meter show 0.00 ohm?5) Clear focused pictures of the inside pcb would help us.6) Does the scope work?

content: Hello retiredcaps,Thank You very much for help.Answers:1. No, just stop to work correct. I haven't accident.2. Set the function on DC Voltage and short probe, meter doesn't show 0.00 V DC.Set the function on AC Voltage and short probe, meter doesn't show 0.00 V DC.Set the function on Diode TEST and short probe, meter doesn't show 0.00 V DC.Set the function on Continuity and short probe, meter doesn't show 0.00 V DC.3. Set the function on Resistance and open probe, meter show around 4.6 MOhm.4. Set the function on Resistance and short probe, meter show 0.0 Ohm.Resistance work correct.5.

content: 7) Using another multimeter, what is the input impedance of the MS-2000 when it is turned on and set to DCV? On most meters, it should be around 10M ohm.8] What reading do you get when you short the probes when the MS-2000 is set to DCV? Is this reading steady or it is fluctuating? You say it is not 0.00, but what is the actual reading?9) In the attached picture, I marked the following components. For the following, you can measure them all "in circuit".a) R65 (green arrow) looks like brown black red (1k ohm), likely a fusible resistor. With another meter, what is the reading?b) 2 blue colored PTCs (blue arrow). Each should read between 500 and 1500 ohms. With another meter, what is the reading of each?c) spark gap (white arrow). Each should read open circuit with another meter set to measure its resistance. With another meter, what is the reading of each?

content: 7. Input impedance isn't stable it is fluctuate:on range 400mV is from 1.4 to 3.1 MOhmon another range is from 13.5 to 15 MOhm8. Voltage is fluctuating always.9a. Resistor colors are brown, black, brown (100Ohm) i measure 101Ohm.9b. I measure two PTC without desoldering from PCB and value are 1.3 and 1.7kOhm. Tomorrow i will desoldering and will check again.9c. Two spark gap have resistance around 57MOhm.P.S.Before few days i find circuit on METEX DG SCOPE 20Mhz and i see that DMM part is the same on my METEX of 95%. See page 19 Analog DMM Part.http://www.produktinfo.conrad.com/datenblaetter/125000-149999/126560-sp-01-en-DG_SCOPE_20MHZ.pdf

content: Quote from: jstanchev on October 14, 2015, 06:26:16 pmPTCs are likely good. Leave them in there for now.QuoteDesolder both spark gaps and retest your meter to see if it works. Measure both spark gaps out of circuit and report your reading.QuoteI will download and look later.

content: If the schematics are somewhat close, the PTC is 1.5k ohm so your readings of 1.3k and 1.7k are likely good.The spark gap is AG20P (datasheet attached). If I'm reading it right, the insulation resistance is 10000min  or 10G ohm. This suggests the spark gaps you measured are suspect and may be bad.The meter will work with the spark gaps removed, but you won't get any input protection. If the meter is fixed, you can then order replacements.

content: Okay, let's try this.The MAX134 IC pinout is attached. Pins 18 through 22 is where the input divider readouts are.10) Put your meter on DCV. Short Volt to COM using a shorting plug or aligator clip. Using another meter, measure pins 18 through 22 and report your readings for each pin.11) Put your meter on DCV. Use a CR2032 cell or 3V source and feed it into the MS-2000. Using another meter, measure pins 18 through 22 and report your readings for each pin.12) With the two spark gaps removed, do those spark gap solder pads read open circuit?

content: Yes, the input impedance looks like a problem. Normally there's no problem measuring the dc resistance of the front end of a working powered-up meter, but if there's current leaking in somewhere, it will throw off the measurement. Reversing the leads will show inconsistent readings. You may even be able to measure a voltage on the input jacks of the problem unit with a regular 10Meg DMM. As mentioned, often the root cause of the current leakage is PCB contamination from electrolytic caps, batteries, or flux residue.

It should be stable and steady at 5V or 9V according to the datasheet. A scope should also show low ripple on this V+ rail.

content: Quote from: jstanchev on October 16, 2015, 10:47:04 amFrom the datasheet and schematic, the 10M ohm resistor is not involved when the meter is in 400mV range. It is, however, used in the 4V to 1000V range.So I'm not sure if the 125mV reading on the 10M ohm input pin is correct or not when the MS-2000 is set to 400mV.QuoteWith the probes shorted (0V) and the MS-2000 set to 4V range, the input divider should show 0.0mV on the 10M and 1.11M pins. Since there is voltage on those pins, something is definitely wrong.QuoteWith a 3V source and the MS-2000 set to the 4V range, the input divider should show a steady and stable 300mA on the 10M and 1.11M pins.QuoteAre the above measurements the spark gap solder pads?QuoteI saw that earlier, but didn't comment on it. With open probes, it should show open circuit instead of 4.6M ohm.

content: Hmm, I have some more suggestions.14) The readings above suggest that the MS-2000 in the 400V range might be working? Can you measure the large filter capacitor of a SMPS? It should be around220VAC x 1.41 = 310VDC. It should be steady and stable.15) The 400mV range might be working. Can you test something in that range?16) I think some of the readings could be due to leakage current. A isopropyl alcohol (IPA) bath with a clean toothbrush scrubbing might be in order (both sides of the DMM pcb). Let it dry thoroughly, overnight or use a fan, before reassembly.

We want to know if the DCV 400V range on the MS-2000 is working correctly and giving stable readings.QuoteIt is possible the MAX134 is bad, but I would give the pcb an IPA bath before coming to that conclusion.

content: Hi all,I found this thread because I had the same issue with my multimeter, mine is a Tenma 72-6640, another re-labelled Metex MS-2000.I followed all the suggestions given, but I also had a blown resistor, the 1Kohm resistor labelled R221 in the DG Scope schematic and R52 on the DMM PCB, thanks to jstanchev for confirming me its value. I reaaly have no idea how I blew that resistor, but it helped me in finding the solution.Thanks to the schematic I traced the signal path in the input stage and I found the protection transistors not shorted, but somehow damaged, they are Q59, Q60, Q61 and Q62 in the schematic, Q17, Q18, Q19 and Q20 on the PCB. To test the possible solution, I removed Q17 and Q19, in testing the DMM I had to be careful because there was no protection against either to over voltages (especially in the 400mV range), or to DC/AC voltages while measuring resistances. I did not use the auto range feature to be sure not to damage the MAX134.The schematic diagram lists two possible types for these transistors, in my case they are KTC3875S Y-RTK. I replaced all four of them and of course the blown 1K resistor.After replacement I cleaned with the ultrasonic cleaner both PCBs (not the one with the keyboard and the one with the display) with a 30 minutes bath in IPA at 50°C, then I "baked" the PCBs in the oven at 50°C for 10 minutes to let the alcohol evaporate completely.Now everything works perfectly, input impedances are in specification, about 10MOhm in all ranges. I also measured resistors, capacitors (down to 115pF), DC and AC voltages, I tested also the frequency meter. Great!I considered also the contamination issue. This may be possible because of the semi-sealed design of the DMM case and because of the rechargeable NiMh batteries inside. My issue started when the battery pack began losing its capacity, probably some exhalations from it caused loss of insulation between the traces and/or the components, considering also that I work with vacuum tubes and high voltages, this combination might have caused the resistor to burn and the subsequent damage to one ore more protection transistors. Anyway, now it is fixed but I will not use the autoranging feature for measuring high AC or DC voltages, the switch between 400mV and the higher ranges is done by a relais that might not be sufficiently fast.Now I'm trying to restore the rechargeable battery pack, unfortunately I lost the old one after moving to the new house, if someone can post pictures of it and its schematic it would be very helpful. I do not remember if it has 2 wires (in this case no problem, one is the positive, the other one is the negative pole), or if they are 4 and this would be an issue, what are the other 2 for???Thank you all for the suggestions.

content: Hello yuraol, I did bot find any schematic of this meter, in this thread you can find the METEX DG SCOPE 20Mhz schematic whose DMM part is the same as the MS2000.http://www.produktinfo.conrad.com/datenblaetter/125000-149999/126560-sp-01-en-DG_SCOPE_20MHZ.pdfIf anyone can post the complete MS2000 schematic it would be helpful considering that MS2000 PCB labels are, of course, not the same as the DG SCOPE ones.Thank youStefano
