PCL-726 Calibration

•

output circuit connection figure at 2-9.2 to connect, the digital
multi-meter is also needed to connect into the circuit.

4. Press <PgUp/PgDn> to set the output voltage from each D/A

analog output channel is 0V. Adjust VR1-3, VR2-3, VR3-3, VR4-3,
VR5-3 and VR6-3 to ensure the actual output current from each
channel is 4mA.

4.3.5 Note

1. Both Unipolar and bipolar output voltage. Unipolar output current with –5V

internal reference voltage are all pre-calibrated in the factory. User does
not need re-calibrate before use.

2. Users who use –10V as their internal reference voltage may want to

calibrate before use to minimum the measurement error. Please refer to
4.3.1 to fine tuning VRx-1 precise resistor. For example, Ch2 is used under
–10V internal reference voltage, only VR2-1 need to be fine tuning and so
on and so forth.
