4.1 Testing a Flow Metering System

The CalMaster2 can hold the test results of up to 100 flow meters.
The contrast of the LCD screen can be adjusted by pressing the  and  buttons.
Note.
If there is insufficient battery charge to completely a test, CalMaster2 does not start the
test. Recharge the CalMaster2 – see Section 6, page 40.
If the ambient temperature is greater than the specified operating temperature of 50°C
(122°F), the tests are failed.
Before using the CalMaster2 ensure that the flow metering system has been isolated
from any integrated system – for example, current loops and telemetry.
To perform a test:
1. Connect the CalMaster2 to the flow metering system – see Sections 3.2 to 3.4.
2. Disconnect communications lead 1.
3. Press the 'On' button. The initialization screen appears followed by a connection screen:
Connection
Connect new?
Exp:359 Mem:1.0%
Ok Contrast
Note. 'Exp' is the number of days remaining before the licence expires.
4. The CalMaster2 attempts to connect to the flow measuring system. Select 'Ok'.
5. Reconnect communications lead 1.
6. Once the connection has been established a prompt appears to select whether the pipe is
full:
Connection
Is pipe full?
Yes
Note. When verifying an AquaMaster the pipe must always be full.
7. Select Yes or No. A prompt appears to test the analog outputs:
