AMM-1022
beforehand, set the range selector at the highest
position.
- "
" means the socket of INPUT maximum current is
200mA, over current will destroy the fuse. 10A's
maximum current is 10A, no fuse protection.
4.3 Resistance measurement
- Connect the black test lead to the COM jack and the red
test lead to the Ω jack.
- Set the transform switch at the Ω range position.
- Connect test leads across the resistance under
measurement.
- You can get reading from LCD.
To avoid electrical shock and/or damage to
the instrument, disconnect circuit power and
discharge all high-voltage capacitors before
measuring resistance.
NOTE:
- For measuring resistance above 1MΩ, the meter may take
a few seconds to stabilize reading. This is normal for high
resistance measuring.
- If the resistance being measured exceeds the maximum
value of the range selected or the input is not connected,
an overrange indication "1" will be displayed.
4.4 Diode test
- Set the rotary switch to
- Connect the black and red test leads to the COM and Ω
terminals respectively.
- Connect the red test lead to the anode, black test lead to
range.
