9.5.2 Heater, Display and Keypad Verification
1. Touch the heater plate. If warm, this indicates that the Hydran M2-X is being
heated to maintain the temperature of the sensor close to the corresponding
set point.
2. Ensure the Hydran M2-X is in Main Display mode. For details, see Section
3.1.2.3.
3. Press the Main Menu context key once and ensure the Main Menu is
displayed. Ensure all of the other keys are operating properly.
9.5.3 Parameter Verification
The Hydran M2-X’s operation parameters can be verified using the Hydran M2-X’s
keypad or the Perception software running on the host or laptop computer:
1. Verify all parameters in Alarms > Alarms Setup.
2. Verify the date and time in Setup > Date & Time.
3. Verify the parameters in Setup > Temp. Setup.
4. Verify the parameters in Setup > History Setup > History Log Rate.
5. Verify the parameters in Setup > Comm Setup; these parameters can only be
accessed using the Hydran M2-X’s keypad.
6. Verify all parameters in Setup > Readings Setup.
7. Verify all parameters in Setup > I/O Setup.
8. Verify the operation mode of the five relays in Test > Relay Test.
9. Ensure the two sets of serial numbers, the sensor parameters and the
checksum in Service > Sensor Param correspond to those written on the Test
Certificate and Data Sheet (for an example, see Figure 3-12).
10. Verify the battery voltage and the other parameters in Service > View Service
Data.
11. Verify the operation mode of the TDM signal (Relays/Analog > TDM Out
submenu).
9.5.4 Alarm Relays Verification (If Connected)
Verify the alarm relays only if the Hydran M2-X’s alarm contacts are used
(connected to a SCADA system). For the verification procedure, see Section 4.2.6.
