5.0 Calibration

5.1 Sensor Calibration

This feature allows the sensor to be calibrated. Ensure that the correct sensor type is selected in the configuration prior to

calibration. Refer to section for details of the menu system operation.

5.1.1 Sensor Zero

Tap the magnet over the menu switch, the display will change to Pass, Tap the magnet again on menu display will

show E 1.

Tap the magnet over the enter switch the display will then alternate E: 01 Wait approximately 1 minute and Tap enter.

 If the zero is accepted the display will show ---- Tap the magnet over the menu switch to exit.

 If the zero calibration was not within acceptable range the display will show F2. A recalibration is required; you

may need a cylinder of 20.9 air.

Note: 1. Carbon Dioxide sensors, except for high % range, should be zeroed in air due to the background levels of CO2

present. These sensors are best zeroed while being exposed to 100% nitrogen.

2. Where a purging gas has to be applied, use a flow rate of between 0.5 and 1.0 L/min. Allow sufficient time for

the sensor to respond.

5.1.2 Sensor Span

Tap the magnet over the menu switch, the display will change to Pass, Tap the magnet again on menu display will

show E 1.

Tap the magnet over the up switch, the display will change to E 2.

Tap the magnet over the enter switch the display will flash E: 2 and XX (XX = the calibration gas level).

Caution:

Be sure that the calibration gas you use matches the type and concentration of calibration gas display on the EX-

6120, 6165 S

ERIES

If the calibration gas you have does not match the displayed value, place the magnet over the up or down switch to

adjust the value.

Tap the magnet over the enter switch, the display will flash E: 2

Apply the calibration gas. The display will flash E: 2 and a number (sensor response to gas) when the number stops

changing,

Place the magnet over the enter switch. The display will show ---- if the calibration was successful.

Tap the menu switch to exit and remove the calibration gas.
