5 OPERATION AND CALIBRATION

5.1 OPERATION

Note:

BEFORE turning on the main power to the monitor, MAKE SURE all connections are

properly made.

When power is applied, the GREEN power LED will light. A one-minute time delay eliminates

false alarms from occurring during the sensor's warm up period. After this time delay, the unit

becomes fully operational. If time delays are required or the audio alarm indicator is not

needed, the three circuit miniature switch can be set accordingly. Refer to Section 3, Item 9 and

Figure 1.

If any gas surrounding the sensor exceeds the low alarm trip point setting, the yellow LED and

low alarm relay will be activated. If any gas exceeds the high alarm trip point setting, the red

LED, high alarm relay and audio alarm will be activated. An open sensor circuit is indicated by

the amber fail LED.

5.2 CALIBRATION

As the calibration procedure may cause the monitoring equipment to give a false alarm,

appropriate precautions should be taken. Instructions on introducing the gas sample are

included with the calibration kit or available separately (depending on type of gas or application).

To observe immediate reaction during calibration, the low and high alarm time delays should be

disabled.

5.2.1 EQUIPMENT REQUIRED

•

Digital multimeter

•

Miniature screwdriver

•

Calibration gas(es)

•

Calibration Kit (number?)

5.2.2 ADJUSTMENTS

For full recalibration adjustments, follow the Set-Up Procedure steps 1 to 5 inclusive. There are

two adjustments to be made for periodic recalibration: Zero and Span adjustments and the

Alarm adjustments. Alarm adjustments are only required if the user wants to change alarms.

Refer to Figure 6 to perform the following procedure

1) Remove cover from monitor enclosure.

2) Plug in standard test leads fully into jacks on multimeter.

3) Switch ON multimeter and select the DC Volts range greater that 1.00 VDC.
