2 420 Plus/420HE Analog Output Card Installation Instructions
420 Plus Enclosure Reassembly
Once cabling is complete, position the backplate over
the enclosure and reinstall the backplate screws. Use
the torque pattern shown in Figure 2 to prevent
distorting the backplate gasket. Torque screws to 15
in-lb (1.7 N-m).

Once cabling is complete, close the front cover of the
indicator and hook the draw latches.

Analog Output Calibration
The following calibration procedure requires a multimeter to measure voltage or current output from the analog
output module. No test weights are required for calibration.
NOTE: The analog output must be calibrated after the indicator itself has been configured and calibrated.
Figure 4. Analog Output Menu
1. Enter setup mode and go to the ALGOUT menu
(see Figure 4).
• 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
To enter MIN and MAX values, use the and
keys to select the digit; use the numeric
keypad or the and to increment or
decrement the value.
2. Connect multimeter to analog output:
• For voltage output, connect voltmeter
leads to pins three and four
• For current output, connect ammeter
leads to pins one and two
3. Adjust zero calibration: Scroll to the TWZERO
parameter. Check voltage or current reading
on multimeter. Press and hold or to
adjust the zero value up or down.
4. Adjust span calibration: Scroll to the
TWSPAN parameter. Ch eck voltag e or
current reading on multimeter. Press and hold
or to adjust the span value up or down.
5. Final zero calibration: Return to the 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.
