Overload protection: 250V DC or 250V AC RMS
Note: It is normal once the small value of capacitance dose not return zero,
deduct the readings during measurement for getting the accurate value.

Operation
10.1
DC + AC VOLTAGE MEASUREMENT
Do not measure circuits that may contain voltages > 1000 VDC or
> 750 VAC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.
Always place your fingers behind the protective edges of the test
probes while measuring!
1.
Insert the red test lead into
“°C/°F V
Hz % mF”
jack and insert
black test lead into “COM” jack.
2.
Set the rotary switch to the voltage (V) position
3.
Touch the black test probe tip to the negative side of the circuit; touch
the red test probe tip to the positive side of circuit.
4.
Read the voltage in the LCD display. The polarity of red test lead
connection will be indicated when making DC Voltage measurement.
Notes
•
Set the rotary switch to higher range if not known the current
range under test, and then lower down until the best accuracy.
•
To avoid electrical shock and/or damage to the instrument, do
not attempt to take any voltage measurement that might exceed
750VRMS.
