How to Calibrate Redox Probe - ProfiLux 3.1N

Hi,

Please could someone assist and advise how to calibrate the Redox probe?

Info: My ProfiLux front screen does not work so I have to perform changes via the GHL Control Center.

When entering in to Sensor Settings via Remote Control in GHL Control Center and choosing Redox there is no calibration option.

I've reviewed the manual and the programming guide, but unable to calibrate.

Device / Card

ProfiLux 3.1N
Firmwareversion: 6.38

Slot number 2
Name: COND S & REDOX
Class: Analog card
Sensor 1: Conduct.(S)
Sensor 1: Redox

GHL Control Center V1.1.2.1

Any assistance would be greatly received... I must be being dumb.

DOH!!!

Disabled probe whilst away and forgot to enable before attempting to calibrate hence no option on menu.

Hopefully my mistake may assist someone else.

Happily calibrating now.

OK have calibrated but the values are wrong.

On calibration the ADC values look as follows.

ADC1: 4 (0mv)
ADC: 3 (230mv) (calibration fluid 230mv)

When placing the probe in the 230mv calibration fluid after calibration the value jumps from -1 to 2mv,

The probe has been in the sump for a four weeks, at first active and not calibrated, crazy high readings. Then not active for 2 weeks and now active and then calibration has been performed and the readings are again wrong, but totally the other way.

Anyone know what the best options going forward to resolve?

This is a new Neptune Lab Grade probe.

Changed the signal strength from strong to weak and wider fluctuation.

Attachment 11530

Use remote Control in profilux Control center

That's what I used to calibrate the probe with.

Has anyone else had such weird results after calibrating?

I have calibrated the Redox probe three times with the null plug and 230mv fluid with the same results.
