CALIBRATION
INSTRUCTIONS Performing a Manual Calibration with a Membrane Keypad
1. Place the control loop in manual.
2. Press the CAL key. The CAL LED will light solid.
3. Apply the first calibration gas.
4. Press the CAL key. When the unit has taken the readings using the first
calibration gas, the CAL LED will flash continuously.
5. Remove the first calibration gas and apply the second calibration gas.
6. Push the CAL key. The CAL LED will light solid. When the unit has
taken the readings using the second calibration gas, the CAL LED will
flash a two-pattern flash or a three-pattern flash. A two-pattern flash
equals a valid calibration, three-pattern flash equals an invalid
calibration.
7. Remove the second calibration gas and cap off the calibration gas port.
8. Press the CAL key. The CAL LED will be lit solid as the unit purges.
When the purge is complete, the CAL LED will turn off.
9. If the calibration was valid, the DIAGNOSTIC ALARMS LEDs indicate
normal operation. If the new calibration values are not within the
parameters, the DIAGNOSTIC ALARMS LEDs will indicate an alarm.
10. Place the control loop in automatic.
