Pay attention to electric shocks when measuring high voltage.
•
After completing all measurement operations, disconnect the test pen from the
measured circuit.
•
When the measured voltage is higher than the safety voltage of 30V AC, the meter
LCD displays the high voltage warning prompt.
•
When inputting overvoltage, higher than 750V AC gear range, the meter will
automatically sound intermittent buzzing and the high voltage warning prompt will
automatically flash.
•
AC conversion adopts the AC coupling true RMS response mode, sinusoidal input
for correction.
•
The accuracy of non-sinusoidal wave shall be adjusted as follows:
- Crest factor 1.4~2.0, accuracy should be increased 1.0%,
- Crest factor 2.0~2.5, accuracy should be increased 2.5%,
- Crest factor 2.5~3.0, accuracy should be increased 4.0%.
DC VOLTAGE MEASUREMENT
•
Insert the red test pen into the “V” jack and the black test pen into the “COM” jack.
•
Push the function range switch to the DC voltage measurement and connect the
test pen in parallel with the power or load to be measured.
•
Directly read the measured resistance value from the display.
Note:
•
Insert the red test pen into the “Ω” jack and the black test pen into the “COM” jack.
•
Push the function range switch to the measurement gear “Ω”, press

RESISTANCE MEASUREMENT

•
Do not input voltage higher than 1000V. It may be feasible to measure higher
voltage, but damage will be caused to the meter.
In order to obtain a precise reading when measuring at 600mV gear, the relative
measurement function can be adopted.
Firstly, input the test pen under the short-circuit
condition, press the
REL
button and read the
resistance measurement value. Afterwards, the meter
automatically deducts the test pen displayed value
under short-circuit condition.
Watch out for electric shocks when measuring high
voltage. After completing all measurement operations,
disconnect the test pen from the measured circuit.
When the measured voltage is higher than the safety
voltage of 30V DC, the meter LCD will display the
warning prompt.
When inputting overvoltage higher than 1000V
DC gear range, the meter will automatically sound
intermittent buzzing and the high voltage warning
prompt will automatically flash.
