Megohmmeter Safety
WARNING :
The AT682/683 Megohmmeter can provide an output voltage as high as 1000VDC
to the external device under test (DUT).
Although the AT682/683 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 followed.
The AT682/683 is designed to be operated with its chassis connected to earth ground. The
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.
Tightly connect cable(s) to the (red) 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.
NEVER touch the metal of the High Voltage probe directly. Touch only the insulated parts
of the lead(s).
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 HV LED is lit.
Before turning on the AT682/683, 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.
After each test, press the [DISCH] button for safety. This terminates the high voltage being
applied to the output terminals.
When the HV LED is lit NEVER touch the device under test, the lead wires or the output
terminals.
