3.2.6 Continuity/Diode Test
Function
If measured resistance
is less than 50Ω, the
buzzer will sound.
The display shows the
approx. forward
voltage drop
Overload Protection: 250V DC or AC rms; do not exceed
15 sec. continuous measurement.

4. Operating Instructions
4.1 DC/AC Voltage
Warning
Max. input voltage: 600V DC or AC rms (200mV
range is 250V DC or AC rms).
Do not exceed the protection limits to prevent
electric shock and/or damage to the meter.
• Turn the rotary switch to the proper voltage range.
• Connect the red test lead to the V input jack and the black
test lead to the COM jack.
• Connect the leads to the voltage source or circuit under test.
• Read the measured voltage on the display.When measuring
DC voltage, the display will show the polarity of the red lead.
• If the display only shows "1", it indicates the input exceeds
the selected range.Move the rotary switch to a higher range.
4.2 Resistance
Warning
Turn off all power and discharge all capacitors
completely before making resistance
measurements.
•
Turn the rotary switch to the proper voltage range.
Connect the red test lead to the Ω input jack and the
•
black test lead to the COM jack.
•
Connect the leads to the resistance or circuit under test
and read the measured resistance on the display.
•
When measuring low resistances, short the test leads
and record the measurement.Then connect the leads to
the resistance to be measured and subtract the shorted
resistance.
