4-1 Switches/buttons and description○Power switch and function switch
Turn this switch to turn on and off the power and to select thefunctions of V, Ω/● /●, , μA, mA, A.
○Range hold button
Pressing this button once sets the manual mode and the range isfixed. ("AUTO" on the display disappears)
Once the manual mode is set, the range moves each time thisbutton is pressed. Checking the unit on the display and the placeof the decimal point, select a desired range. To return to the automode, keep pressing this button until "AUTO" on the display
appears.
○Data hold button
When this button is pressed, the data display at that time
continues ("DH" lights on the display). When the measuring inputchanges, the display will not change.
When this button is pressed again, the hold status is canceled you
can return to the measuring status. ("DH" on the display disappears.)○Select button
When this button is pressed (→), the each modes change asfollows.

○Auto power save
This instrument incorporates the auto power save function thatturns off the display in about 16 minutes to save the battery draining.
When the rotary switch or a switch button is not controlled while
this instrument is ON, the warning buzzer beeps in about 15
minutes and then the instrument power and display are turned off
automatically in 1 minute after. Every time a switch button ispressed or the function switch is switched during measurement,
the time until the auto power save function is activated isextended by about 16 minutes.
To recover from the auto power save mode where the display isoff, press one of the three switch buttons.
This function can be disabled by holding the SELECT button whileturning the function switch to switch the power ON.
When this function is disabled, theindicator on the display is
extinguished.
As a small amount of the battery power drains even when the
instrument is turned OFF by the auto power save function, be
sure to set the rotary switch to OFF when not using the instrument.
○OVER LOAD (O.L) indication
In case of excess input to this device, the indicator displays O.L. If
O.L is displayed during the voltage function, stop the input immediately.
When a DC 1000 V or higher voltage is input while the DCV
function is selected or when an AC 750 V or higher voltage is input
while the ACV, Hz or Duty function is selected, the instrument
generates warning with intermittent buzzer beeps and the flashing LED.

Example of DC 60-600 mA range measurement
Note:● As this instrument employs the mean value method for the AC detection,measurements become erroneous when the input waveform is otherthan a sine wave (the frequency range is 45 to 500 Hz).
● The current measured with this method decreases by the amountthat the internal resistance of the current range is inserted inseries. The effect of this phenomenon is particularly noticeable
when measuring the current of a low-resistance circuit.
The resistance value of the μA range is about 50 Ω while that of
the mA range is about 0.5 Ω.
● If the displayed value hardly changes when the input signal isapplied or becomes much lower than expected, the measurement
terminals or function switch are set erroneously or the fuse
(φ6.3 x 32 mm size, 0.4 A/1000 V) may be blown. Please check them.
● The μA/mA switching is performed with the rotary switch.
● The DC/AC switching is performed with the SELECT button.

2.The current measurement is accompanied with heatgeneration. When measuring current of 6 A or more,
complete each measurement within 10 seconds and leavean interval of 5 minutes or more between measurements.

5-11 How to use optional products
5-11-1 Measurement using the DC high-voltage probe (HV-60)
Maximum measurable voltage: DC 30 kVWARNING
1. The HV probe is designed to measure low-current circuitry. Do
not use it to measure high voltages of power transmission line, etc.
2. Do not apply a voltage higher than the maximum measurable voltage (DC 30 kV) of the probe.
3. Do not change the function during measurement.
4. Do not turn the rotary switch to change the function during
measurement.
1) Measurement target: Anode voltage of a cathode ray tube,
voltage of high-impedance circuitry such as a high focusing voltage.
2) Measurement range: DC 1000 V.
3) Measurement procedure
Connect the red plug of the HV probe to the + measurement
terminal and the black plug to the COM (－) terminal.
Set the function switch to “DCV” and the range hold button to
the DC 1000 V range.
Connect the black clip to the ground line of the measurement target
and apply the pin on the tip of the HV probe to the measured point.
Read the displayed value by multiplying it by 0.1. The unit of
the obtained value is kV.
After the measurement, remove the pin from the measurement target and then disconnect the clip.
●The HV-60 cannot be used for AC voltage measurements.

◎Accuracy calculation method
Example) DC voltage measurement (DC mV)
True value: 100.0 mV
Range accuracy: 600 mV range - ±(0.5 %rdg + 2 dgt)
Tolerance: ±(100.0 [mV] x 0.5 % + 2 [dgt]) = ±0.7 [mV]
Displayed value: 100.0 [mV] ± 0.7 [mV] (within the range of 99.3
to 100.7 mV)
CAUTION:
If there is presence of strong magnetic field generated byconductor fed large current, motors or strong radio wave, ameasurement may not be accurate.
