4. Operating instructions
4.1 AC/DC Voltage measurement
•
Set the rotary switch to the AC or DC voltage position.
•
Connect the red test lead to the input jack and the
black lead to the COM jack.
•
Connect the leads to the circuit under test and read the
measurement on the display. Observe polarity for DC
measurement. In manual mode, if “
OL
” is display it
means the measurement has exceeded the current
range. Increase the selected range and measure again.
WARNING
Do not measure voltages higher than 600V DC or AC rms to
prevent damage to the meter or personal injury.
WARNING
Never measure open-circuit voltages exceeding 600V between
the
input terminals and ground to prevent injury or damage to
the meter.
4.2 AC/DC Current measurement
•
Turn off power to the circuit. Allow all capacitors to
discharge.
•
Set the rotary switch to the appropriate AC/DC current
voltage.
•
Press “FUNC” to switch between AC and DC current.
•
Depending on the current to be measured, connect the
red test lead
to either the input or 10A jack and the black
lead to the COM jack.
•
Break the circuit and connect the leads in series with
the circuit (black
lead on the lower voltage side).
• By Hz range:
- Input voltage range: >2V AC (True-RMS)
( higher input voltage at higher frequency )
- Max.input voltage: 600V AC (True-RMS)
