Cleaning
To clean the instrument, wipe it gently with a soft cloth moistened with water or mild detergent.
Troubleshooting
Symptom
• The instrument is indicating
an abnormal measured
value for current.
36
Verification and/or Solution
• Is the measured current value too small for the instrument's measurement
range?
Wrap the wire around the clamp sensor one or more times. Each additional
wrap of the wire will increase the measured value, so that wrapping it once
yields a measured value that is twice the actual value and wrapping it
twice yields a measured value that is three times the actual value.
• Are the tips of the clamp sensor's jaws open?
• Is the clamp sensor damaged?
If the sensor is damaged or cracked, it will not be able to measure current
accurately. Send the instrument for repair.
