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.
