7. Measuring procedure
This tester provide five main functions and four minor functions:
Main Functions:
1. 500V voltage insulation resistance test.
2. 1kV voltage insulation resistance test.
3. 2.5kV voltage insulation resistance test.
4. 5kV voltage insulation resistance test.
5. AC/DC voltage measurement.
Minor functions:
Function 1 ─ Date/time adjustment.
Function 2 ─ Measurement time setting.
Function 3 ─ Display data stored.
Function 4 ─ Delete data stored.
(A) Insulation resistance measurement test (main function)
Note:
1. Before test performed, be sure that no voltage is made
on the specimen. If voltage exists therein, remove the
power supplied.
2. To secure operator’s safety, check if there is any damage
on the tester or test cable.
3. During the test, do not touch the metal on the specimen
surface or test cable.
4. Wear insulation gloves and rubber shoes while operating
this high-voltage measuring instrument.
(a) Checks before test is performed:
Press the power switch and check if power supply is
sufficient? If insufficient, "Low Battery" will be displayed on
the LCD display. Please replace with new
Alkaline
batteries.
