Risk of
shock
When performing a high voltage test the CH+ tester limits
the applied current to 1.5 milliamps and the applied charge
to 45 micro coulombs. These electrical levels are
considered safe for adults; however, some people could be
affected adversely even at these levels. For this reason
avoid touching the high voltage. Whenever possible using a
DC voltage for high voltage testing provides an added level
of operator safety.
Conditions for Operation
Your CH+ Tester is intended to be used indoors at a temperature of 10 to 40 degrees
Celsius. Best performance can be obtained at a relative humidity less than 70%. Insulation
Resistance Measurements will degrade over 70% relative humidity. The unit can be
mounted in a ventilated compartment. Be sure not to block the vents on the sides and back
of the tester.
Never apply live voltages to the test points or probe input of your Cirris tester. Power
supplies and other accessories not approved by Cirris may cause damage or present a
hazard. If you use a Cirris product in a manner not specified in this manual and the
accompanying help system, the protection provided by the product may be impaired.
