Model 5100-XX-IT Toxic Gas Sensor Module

5. CALIBRATION

5.1CALIBRATION FREQUENCY

The 5100-XX-IT has been calibrated in the factory prior to shipment. It is recommended that the user check calibration before placing in service. The toxic sensor module must be calibrated every six months. Periodic functional tests are advisable for critical applications and hostile environments.

The sensor module microprocessor software includes high level self checking algorithms which provide continuous sensor diagnostic and self adjustment. Users may elect to increase calibration periods based on low drift experience during the first two calibration periods.

5.2CALIBRATION PREPARATION

Calibration of the Toxic Gas Sensor Module is accomplished by simple menu based steps and application of span gas.

NOTE

If an error is made during any stage of the calibration process, hold the magnet stick at the Switch [M] for 10 seconds. A scrolling display will indicate “Calibration aborted” and the sensor module will exit the calibration activity and return to normal operating mode. The calibration procedure can then be restarted

Calibration must be performed only when the area is known to be clear of the applicable toxic gas. If necessary, use a portable instrument to confirm that there is no background toxic gas.

For compliance with Factory Mutual (FM) Apparatus, the Sierra Monitor Model 1250-01, 1256-01, 1260-XX are the only FM Approved calibration gas delivery device. Use Model 5358-00 or 5358-01 Calibration Adapter or Model 5360-00 Gas Delivery Fitting.

5.2.1 CALIBRATION GAS DELIVERY METHODS

Calibration gas is can be delivered to the sensors via the following delivery devices: Model 5358-00: Calibration Adapter - used with portable calibrators. See 5-1.

Model 5360-00: Calibration Gas Delivery fitting - permanently installed fitting which allows tubing to be run to a convenient delivery location

5.3CALIBRATION PROCEDURE

Table 5-1 shows the step by step process of the calibration procedure.

The procedures requires that the menu “keys” be activated using the magnet stick. Each key press steps through the process of setting the zero value for clean air and then setting the span value.

At each of these steps, apply calibration gas of the value corresponding to the setting accepted on the sensor module display.
