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.

- 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
