YX360TRF̲04̲B4̲初 11.5.12 9:31 AM ページ2MEASURING PROCEDUREWARNING
Confirm the range of use before measurement.
Preparation for Measurement
1 Adjustment of meter zero position:
Turn the zero position adjuster so that the pointer may alignright to the zero position.
2 Range selection:
Select a proper range for the item to be measured and set
the range selector knob accordingly.

NOTE
When determining a measuring range, select a one higher
voltage than the value to be measured as well as where thepointer of a meter moves to a considerable extent.
However, select the maximum range and measure in casethe extent of value to be measured can not be predicted.
Measuring DCV
1 Set the range selector knob toan appropriate DCV range.
2 Apply the black test pin to thenegative potential, and the redtest pin to the positive potential of the circuit.
3 Read the movement of thepointer by V and A scale.

Measuring ACV 〜
1 Turn the range selector knob to an appropriate ACV range.
2 Apply the test leads to the circuit to be measured.
3 Read the movement of the pointer by V and A scale. (UseAC 10 V scale for 10 V range only.)• Since this instrument provides
the mean value system for its AC
voltage measurement circuit, ACwaveform other than sine wave
may cause an error.
• Errors occur under such frequencies other than those in the speciFig. 4fication table.

WARNING
Connect the meter in series with the load.

Measuring ±DCV (NULL)
1 Set the range selector knob toan appropriate ±DCV (NULL)
range.
adjuster so
2 Turn the 0 Ωthat the pointer may alignexactly to 0 by ±DCV scale.
3 Apply the black test pin to thenegative potential side, andthe red test pin to the positive
potential side of the circuit.
4 Read the movement of the pointer by ±DCV scale.

1 Turn the range selector knob to an appropriate DCA range.
2 Take out the circuit to be measured and apply the black test
pin to the negative potential,
and the red test pin to thepositive potential of the circuit.
3 Read the movement of thepointer by V and A scale.
Fig. 5WARNING
Do not measure the resistance in a circuit wherea voltage is present.
1 Turn the range selector knob to an appropriate Ω range.
2 Short the red and black test pins and turn the 0 Ω adjuster sothat the pointer may align exactly to 0 Ω. (If the pointer fails
to swing up to 0 Ω even when the 0 Ω adjuster is turned
clockwise fully, replace the internal battery with a fresh one.)
3 Apply the test pin to measur
resistance.
4 Read the movement of the pointer by Ω scale.
Note: The polarity of + and - isreverse to that of the test
leads when measurement isdone in Ω range.

Note: How to replace battery.
1.5 V×2
1 Loosen the screws fixing the rearcase and remove it.
2 Replace R6 (UM-3) to fresh drybatterise.
3 Put back the rear case where it
was, and fix it with the screws.
Note: Be sure to use the same ratedFig. 7
fuse. In case a fuse other than
the same rate (see “SPECIFICATIONS“) is used, an error inindication occurs and/or circuit protection is made unable.

Measuring Capacity (C)1 Set the range selector knob to C(µF) .
2 Measure the capacitance by applying
the test pin to the capacitor to be measured after the 0 Ω adjustment is madein the same manner as in the resistFig. 8ance measurement.
3 The pointer moves full scale by the charge current to thecapacitor. However, the pointer gradually starts returning to its
original position. Read the indicated maximum value on C(µF)
scale.
Note: Be sure to short circuit the both ends of the capacitor fordischarge prior to the initial measurement or in such caseafter the measurement is made.
Note: Pay due attention to the polarity (+ and -) of the capacitor.
(Connect + side of the capacitor to - side of the meter.)
Measuring AF Output (dB)dB (decibel) is measured in the same way as the ACV
measurement, but by reading the dB scale instead.
For measurement on the 10 V range, the dB scale (- 10 dB ~+22 dB) is read directly, but, when measured on the 50 Vrange, 14 dB is added. On the 250 V range, 28 dB is added tothe reading on the scale, and on the 1000 V range, 40 dBadded.
Thus, the maximum dB readable is 22 + 40 = 62 (dB) measured on the 1000 V range.
Note: Cut direct current with a capacitor of 0.1 µF or more whenmeasuring such signal as having direct current.

ranges are normal (check other parts for any failures).
Storage and Other Precautions
1 Avoid giving the meter any excessive shock or vibration byloading it on the motorbike, for instance.
2 Keep off dust and moisture from the meter.
3 Do not leave the meter for a long time in places of a hightemperature (higher than 55 ˚C), a high humidity (higher than80 %), and dew condensation.
