0.1 Maintenance and Inspection
■ To ensure the safe operation of this unit, perform maintenance regularly.
・If the unit has been subject to moisture, or if oil and dust have accumulated
in the unit interior, the danger of electrical shock or fires resulting from the
deterioration of insulation increases greatly. If the unit is ever subject to
excessive moisture, oil, or dust, cease use immediately, and return the unit
to us for maintenance.
・Periodic calibration is necessary to verify and maintain accuracy.
If calibration becomes necessary, return the unit to us for maintenance.
・This product uses a lithium battery to back up it’s memory. As the battery
power is consumed, it’s ability to store measurement conditions diminishes.
In the event that measurement conditions can no longer be stored, please
contact the manufacturer for repair service.
・Spare and replacement parts for this product are guaranteed to be available
only until 7 years after manufacture of this model is terminated.

leads wiring, fuse blowing, and the "Troubleshooting" list. If a problem is
