1. Connect up the instrument according to the table above.

2. Set the input source to 0.00 mV.

3. Adjust the TARE to give 0.00 mV across the test points (multimeter

two). Do not over-adjust.

4. Turn the ZERO adjustment until the output is at ‘zero’.

5. Se

t the input source to ‘full scale’.

6. Adjust the SPAN

control until the output is at ‘full scale’.

7. Recheck the ZERO adjustment.

To set the excitation voltage for remote sensing mode:

1. Connect up the instrument as above.

2. C

nnect a DVM across the test points marked Ex+ and Ex–.

3. A

djust the EX control until the voltage is correct.
