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.
