Testing for Transducer Leakage Current
Note
Perform the Leakage Test only if the Conductivity Test passes.
1. Select
LEAKAGE.
2. Press
the
ON/TEST button to perform a leakage
measurement.
The green PASS light illuminates if the transducer passed the
leakage current test. The red FAIL light illuminates if the transducer
failed the leakage current test. If there is less than 20
μ
A of leakage
current, the red light pulses, indicating a possible open circuit
condition with invalid test results.
Maintenance
Your ULT800 needs little maintenance or special care. However,
treat it as a calibrated measuring instrument. Avoid dropping or
other mechanical abuse that could cause a shift in the calibrated
settings.
