Maintenance and Safety Considerations

1.1. Calibrating the Meter

All the instruments have analog circuitry: preamplifiers, filter, etc.-whose
performance can change over time. A regular schedule of calibrations will keep
your instrument in optimal condition to support you design, troubleshooting, and
manufacturing work.
It is recommended to calibrate and verify the instrument at least once a year to
ensure that the instrument meets the original designed performance and
specifications.
To avoid damaging the default calibration data stored in a non-violated memory,
a calibration to the instrument can only be done by an authorized service center
and qualified personnel with appropriate equipment.
For detailed information on the calibration procedures, please contact factory or
authorized distributor.
Environmental condition: Calibration or verification test should be performed
under laboratory condition whereby the ambient temperature or relative
humidity can be controlled.
Warm up: Allow up to at least 5- minutes warm- up before performing calibration
to the instrument. After exposure or storage in a high humidity (condensing)
environment, relative recovery period is required essentially.
