The 1865 Megohmmeter/IR Tester can provide an output voltage as high as 1000VDC to
Although the 1865 unit is designed with full attention to operator safety, serious hazards
could occur if the instrument is used improperly and these safety instructions are not
1.
The 1865 unit is designed to be operated with its chassis connected to earth
ground. The 1865 instrument is shipped with a three-prong power cord to provide
this connection to ground. The power cord should only be plugged in to a
receptacle that provides earth ground. Serious injury can result if the Sentry unit
is not connected to earth ground.
2.
Tightly connect cable(s) to the (green) GND terminal. If this is not done, the
DUT's casing can be charged to the high voltage test level and serious injury or
electrical shock hazards could result if the DUT is touched.
3.
Never touch the metal of the High Voltage probe directly. Touch only the
insulated parts of the lead(s).
4.
Never touch the test leads, test fixture or DUT in any manner (this includes
insulation on all wires and clips) when the high voltage is applied and the red

5.
Before turning on the 1865 unit, make sure the AC power cord is plugged into
the proper voltage source and that there is no device (DUT) or fixture connected
to the test leads.
