Insulation Tester
Safety Information
3
• Do not use test leads if they are damaged. Examine the test
leads for damaged insulation, exposed metal, or if the wear
indicator shows. Check test lead continuity.
• Do not use and disable the product if it is damaged.
• Do not touch voltages >30 V ac rms, 42 V ac peak, or
60 V dc.
• Keep fingers behind the finger guards on the probes.
• Do not exceed the Measurement Category (CAT) rating of
the lowest rated individual component of a product, probe,
or accessory.
• Accessories rated to 1000V CAT III/ 600V CAT IV are
intended for hands-free use during insulation testing and
are not to be touched while the output of the product
exceeds the accessory’s marked rating. Allow the product to
fully discharge the installation before removing the test
accessory.
• Impedances of additional operating circuits connected in
parallel can adversely affect measurements.
• Use the correct terminals, function, and range for
measurements.
• Do not operate the product with covers removed or the case
open. Hazardous voltage exposure is possible.
• Use only specified replacement parts.
• Do not use the product if the safety shutter is impaired in
any way. The safety shutter prevents access to the test
terminals and charger terminals at the same time.
• There are no user replaceable parts inside the product.
• Use the guard terminal only as specified in this manual.
• Use only recommended test leads.
• Do not use in distribution systems with voltages higher than
1100 V.
