Current Measurement; Voltage Measurement - KPS DCM4000T Manuel D'instructions

DCM4000T
4.9 Measurement preparation
1) Turn the transfer switch to turn on the power. When battery voltage is low (about ≤ 3.6V, LCD
displays " " symbol, replace the battery.
2) " " symbol means that input voltage or current should not be more than the specified value,
which is to protect the internal line from damage.
3) Place transfer switch to required measuring function and range.
4) When connecting line, first connect the common test line, then connect charged test line. When
removing line, remove charged test line first.

4.10 Current measurement

WARNING
Electric shock Hazard.
Remove the probe from the meter before mesuring with current clamp
1) Measuring switch is placed to position A. At this time, the meter is in AC current measurement
state. Choose appropriate measuring range.
2) Hold the trigger, open clamp head, clip one lead of Measurement circuit to be tested in the clamp.
3) Read the current value on the LCD display.
Note:
1) Clamping two or more lines of circuit to be tested simultaneously will not get the correct easuring
results
2) To get accurate Reading, connect the wire to be tested at the center of current clamp
3) " " symbol indicates that maximum input current is 1000 ACA/DCA

4.11 Voltage measurement

WARNING
Electric shock hazard.
Pay special attention to avoid shock when measuring high voltage.
Don't input voltage more than 750Vac T-RMS.
1) Insert black probe to COM jack, insert red probe to INPUT jack, choose appropiated measuring
range.
2) Place transfer switch to AC voltage
voltage measurement state. To measure AC voltage, press FUNC button to enter AC voltage
measurement state
3) Connect the probe with voltage source or both ends of load in parallel for measurement.
4) Read the voltage on the LCD.
Note:
1) In the small voltage measuring range, if the probe is not connected with the circuit to be tested, the
meter may have fluctuating readings, which is normal and caused by the meter´s high sensitivity.
When the meter is connected with the circuit under test, you will get actual measured value
2) On the relative Measurement mode, automatic measuring range is invalid. Manual measuring
or position. At this time, the meter is in the DC
