Teledyne gfc 7000ta Initial O2 Sensor Calibration Procedure, 1.1. O2 Calibration Setup

Getting Started Model GFC7000TA Carbon Dioxide Analyzer

3.8.1. Initial O2 Sensor Calibration Procedure

If your instrument has an O2 sensor option installed that should be calibrated as well.

3.8.1.1. O2 Calibration Setup

The pneumatic connections for calibrating are as follows:

2	at HIGH Span Concentration
Calibrated N

2	at 20.8% Span Concentration
Calibrated O

VENT

Figure 3-16: O2 Sensor Calibration Set Up

O2 SENSOR ZERO GAS: Teledyne Instruments’ recommends using pure N2 when calibration the zero point of your O2 sensor option.

O2 SENSOR SPAN GAS: Teledyne Instruments’ recommends using 21% O2 in N2 when calibration the span point of your O2 sensor option.

3.8.1.2. O2 Calibration Method

STEP 1 – SET O2 SPAN GAS CONCENTRATION :

Set the expected O2 span gas concentration.

This should be equal to the percent concentration of the O2 span gas of the selected reporting range (default factory setting = 20.8%; the approximate O2 content of ambient air).
