Installation, Operation & Maintenance Manual

OXYvisor Optical Oxygen Analyzer

Auto O

 Calibration Setup

To setup the OXYvisor for Auto-Calibration (

AutoCal)

 there are some additional hardware requirements.

•  (QTY 3) Low-Watt Solenoid Valves to operate the Auto-calibration panel. One solenoid for the process 

isolation valve and two for the calibration gases, zero and span.  

• 

External Power Supply with proper Area Classification to power the solenoids.  The OXYvisor has non-

powered on/off digital relays to control the AutoCal routine.   

The AutoCal setup can be setup via the HMI, however it is fairly tedious and it is recommended to use the 

OXYvisor OxygenAnalyzer software provided with the analyzer to set up this routine.  Refer to the OXYvisor 

Software Instruction Manual for detailed setup instructions.
Basic Arrangement and Wiring Details for an AutoCal panel with the OXYvisor is shown in Appendix 

Temperature Sensor Calibration

It is normally not necessary to calibrate the temperature sensor.  However, if there is an offset the temperature 

sensor can be calibrated via a Smart Calibration routine.  The routine allows for either a 1-point offset 

adjustment or a 2-point offset and slope adjustment.  
The analyzer always performs an offset unless a successive calibration is performed with a 15° C differential 

from the first and then is automatically adjust the slope.  Details of the calibration logic are shown here:

Calibration Setup

5.12.6 - Calibration  - Temperature Sensor Calibration

5.12.4.3 - Manual Cal - Two-Point Calibration - Step-by-Step

Two-Point Calibration [Factory Recommended] - 

This is virtually a combination of the Single-Point Zero and Span 

Gas calibrations with an additional rule that all steps must be completed successfully to save and use the 

calibration.
Step 1.  Via the OXYvisor HMI enter the calibration routine 

Calibration Menu/Basic Setup/Manual O2 Calibration

 

Step 2.  Select the 

Cal-Temp

 

ON

 or 

OFF

.  If 

OFF

, enter the correct calibration temperature.

Step 3.  Follow the 

Single Point Calibration (Zero Gas),

 Steps 2 through 6 of section 5.12.4.1

Step 4.  Follow the 

Single Point Calibration (Span Gas),

 Step 2 then Step 5 through 8 of section 5.12.4.2

Step 7.   The screen will show

 “Span Gas O

2

 Live Values.”

  The displayed oxygen value (PV) and secondary PV’s 

are now active and will show the oxygen value as it approaches the span gas value.  If the sensor is out of 

calibration it may not read the precise span gas value..  Once the Phase Angle, Temperature and Pressure 

have become stable, press ENTER to Store the calibration.
 

Note: 

 The values should be steady and not trending up or down. 

   Phase Angle Stability: +/- 0.1° , Temp = +/- 0.2 °C
 

Note:

  The 4-20 mA outputs are held once the calibration screens are entered.  They are released 

 

to the process measurement once exiting the calibration screen or after time-out from inactivity.

Step 8.  Exit via the Escape Key back to the main measurement window.
