5-2-1 Voltage Measurement (DCV,ACV)

Maximum rating input value DC/AC 500 V

1) Applications

DCV : Measures batteries and DC circuits.

ACV : Measures sine-wave AC voltage as lighting voltages.～

2) Measurement procedure

①Set the function switch

“ ” “ ”DCV or ACV function.

②Apply the black test pin

to the negative potential

side of the circuit to measure

and the red test pin to the

positive potential side.

③Read the value on the display.

④

After measurement, remove

th re an blac tes pin froe d d k t s m

the circuit measured.

●The display fluctuates when

the test leads are removed. This is not malfunction.

●

Since this instrument employs the means value system for its AC

voltage measurement circuit AC waveform other than sine wav , e

may cause error.

●

In the AC 4 V ranges a figure of about 3 9 conuts will stay on even if～

no input signal is present.

●The accuracy guaranteed frequency range is 40 Hz to 400 Hz.

parts or wire with hand.

＜＞How to replace the battery

①Remove the rear case

screw with a screwdriver.

②Remove the rear case.

③Take out the battery and replace it with a

new one.

④Attach the rear case and fix it with the screw.

CAUTION

Set a battery with its polarities

facing in the correct directions.

by SELECT switch.

②Press the RELATIVE

switch to make display

show 00.00 nF. (The“ ”REL

mark illuminates in the upper

right area of the display.)

③Apply the black red test pin

to capacitor.

④Read the value on the display.

⑤After mmeasurement, remove the red and black test pins fro

the circuit measured.

●For measurement of 100 nF or below, the display will not stabilize

due to the influence of ambient noise and floating capacity.

●Necessarily splease discharge the electric charge that wa

charged to the condenser before measurement.

●As the capacitance increases, the measuring time becomes longer.

(Example: approx. 5 sec. at 10 µ. Approx.45 sec. at 150 µF.)
