1. Select Device Setup.
2. Select Calibrate.
3. Select mA Loop Calibration.
4. The display tells you to connect a reference meter, press OK.
5. The analogue output value will be set to 4 mA, press OKtoconrm.
6. Enter the actual reading of the analogue output value (from reference meter or from the controller) and
press Enter.
The Searchpoint Optima Plus will collect data and perform the low calibration.
7. When complete, the display shows a message that the unit is ready to perform the high calibration,
press OK.

11. The display shows a note that the Searchpoint Optima Plus will return to normal operation,
press OK.
12. Return to the Welcome screen.
12.8 Congure Internal Alarm Threshold
The internal alarm threshold is used to log events when the gas reading exceeded the threshold. It is also
used as the value to simulate Alarm. The default value is 20 %FSD.
1. Select Device Setup.
2. Select Gas Conguration.
3. Select Alarm Threshold Conguration.
4. Select Alarm Threshold.
5. Enter the new value between 10 %FSD and 65 %FSD, and press Enter.
6. Press Send to send the information to Searchpoint Optima Plus.
7. Return to the Welcome screen.
12.9 Simulation
Searchpoint Optima Plus can simulate Alarm, Fault and Warning conditions. This can be used to test the
response of the overall system. Simulated Alarms, Faults and Warnings will not be recorded in the Event
History.
