10. MAINTENANCE AND MISCELANEOUS
Periodical maintenance, including checking and calibration is required for
the MS-8200 super megohmmeter to perform reliable measurements and
prevent a trouble and accident.
If necessary, ask your dealer or Hioki representative to do such a service as
periodical checking, calibration and routine maintenance.
10.1 Periodical Checking
To keep your instrument its at best condition, the following checking is
required at monthly periods.
1) Check the Rx measuring terminals and input/output terminal block for
integrity.
As the Rx measuring terminals carry a high voltage (100 V to 1000 V,
maximum, depending upon the model and set-up, visually check the
terminals for any crack, loose connection, etc.
Crack and loose connection will lead a trouble and accident.
2) Clean the panels, Rx measuring terminals, and input/output terminal
board with soft cloth.
3) Visually check the LCD display for brightness and clearness.
4) Check the action of the switches and pushbutton switches for smooth
and trouble-free operation.
5) Measure the measuring voltage across the Rx /+ measuring terminals
With a voltmeter. The voltage should be within ±3% of the selected
value.
