What to do if the analog output is incorrect on Honeywell SC?
- U
  utranJul 28, 2025
  To address an incorrect analog output on your Honeywell Measuring Instruments, first, verify the type of analog output (voltage or current) that the channel uses. You can use the DIAGNOSTICS -> DAC FULL SCALE and DIAGNOSTICS -> DAC ZERO SCALE menu items to force the Analog Output to a known output. Then, adjust your readout device, panel meter, PLC, or data acquisition system to match. Also, check the output selection jumpers.

How to fix +OVLD or -OVLD on Honeywell Measuring Instruments display?
- S
  Shannon WongAug 3, 2025
  If you see '+OVLD' or '-OVLD' on the display of your Honeywell Measuring Instruments, ensure all wires are properly connected. If the message persists after removing the load, the (+)Excitation (“+EXC”) or (-)Excitation (“-EXC”) pins might be shorted to the (+)Signal (“+SIG”) or (-)Signal (“-SIG”) pins. If removing the load results in a numeric reading, the transducer may have a high zero offset. You can use the channel’s SETUP menu and set DIAGNOSTICS -> DISPLAY ADC to “ON”; in the RUN mode this will allow the [VALUE] button to display raw A/D readings as a percentage of its full-scale. If the raw A/D readings display more than +/-10% when there is no load on the transducer, the transducer has a high zero offset.

Why are the auxiliary function pins not operating on my Honeywell SC?
- M

  If the auxiliary function pins are not operating on your Honeywell Measuring Instruments, ensure that the AUX1 FUNCTION or AUX2 FUNCTION SETUP menu items are configured correctly; if they are set to DISABLED, they will not function. Also, the Auxiliary Function (“AUX1” and “AUX2”) pins must be connected to pin 10, not pin 8, to activate them.

What to do if Honeywell SC show “APPLY 00000” on power-up?
- J
  Jordan SkinnerAug 14, 2025
  If you see “APPLY 00000” on power-up of your Honeywell Measuring Instruments, reconnect the original transducer to the channel and restart the instrument. Alternatively, press [ENTER] to recalibrate the channel to the new transducer using Shunt or mV/V Calibration and accept the presently applied load as “0”. You can also change the CALIBRATION DATA -> ZERO-SCALE VALUE menu item from “0” to a load that can be applied, or use the CALIBRATE menu item to perform a Known-Load Calibration with the new transducer.

How to reduce EMI/RFI sensitivity on Honeywell Measuring Instruments?

  To reduce sensitivity to EMI/RFI in Honeywell Measuring Instruments, ensure that the shields of the transducer cables are connected to the “cable shield connection screw” on the rear panel of the instrument.
