7.3 Current Output (I02)
1. Attach an ammeter (4 1/2 digit or more) with the negative lead to TB4-1 and
the positive lead to TB4-2 on the rear panel of the unit.
2. Connect a jumper wire between TB4-1 and TB4-3.
3. Set the ammeter range to 20 mA full scale.
4. Apply a signal to the input which displays zero.
5. Record the ammeter reading (5.0 mA is typical).
6. Apply a signal to the input which is equal to the display span (UD - LD) and
adjust R7 (S) on the ammeter to read the output span (UO - LO) plus the
offset recorded in step 5 (16.0 + 5.0 = 21.0 mA is typical).
7. Remove the jumper between TB4-1 and TB4-3.
8. Apply a signal to the input which displays the lower display reading (LD) and
adjust R8 (Z) to read the lower output current (LO) on the ammeter.
9. Apply a signal to the input which displays the upper display reading (UD) and
adjust R7 (S) to read the upper output current (UO) on the ammeter.
10. Repeat steps 8 and 9 above.
