10.7 Analog Output Calibration

The following calibration procedure requires a
multimeter to measure voltage or current output from
the analog output module. If the option is not already
installed, see Section 2.4 on page 7.

1. Enter setup mode and go to the ALGOUT
menu (see Figure 10-5):
• Set OFFSET to 0% for 0–10 V output,
20% for 4–20 mA output
• Set MIN to lowest weight value to be
tracked by the analog output
• Set MAX to highest weight value to be
tracked by the analog output
2. Connect multimeter to connector J1 on the
analog output board:
• For voltage output, connect voltmeter
leads to pins 3 and 4
• For current output, connect ammeter
leads to pins 1 and 2

3. Adjust zero calibration: Scroll to the
TWZERO parameter. Press
value, then check voltage or current reading
on multimeter. Press and hold
adjust the zero value up or down.
4. Adjust span calibration: Scroll to the
TWSPAN parameter. Press
value, then check voltage or current reading
on multimeter. Press and hold
adjust the span value up or down.
5. Final zero calibration:
TWZERO parameter and verify that the zero
calibration has not drifted. Press and hold
or to re-adjust the zero value as required.
6. Return to normal mode. Analog output
function can be verified using test weights.
