Maintenance

Maintenance
When the Cover or the Display is soiled, first wipe away lightly with a clean soft
cloth damped by diluted mild detergent solution and then wipe off moisture with a
dry clean soft cloth.
CAUTION:
Do not wipe the transmitter with solvent such as Thinner.
Periodic inspection
Inspect the following items every 3 months:
Make sure that the Transmitter is fixed securely.
Make sure that the Transmitter is not damaged.
Make sure that the screws of the Terminal Block are not rusted.
Calibration
The SC-T4 is designed so as to make measurements stably for a long time. In
order to maintain the reliability of measurement, however, carry out calibration at
least once a year (Refer to page 10 ([5] Operation (1) Calibration)).
Long-term storage
When the SC-T4 is not used for a prolonged period, turn off the Power Switch
and disconnect the Power Cable from the power supply prior to safekeeping.
