General Information
The Sentry Plus Series Hipot Tester is a measuring instrument for direct readout of hipot output
voltage and leakage current and insulation resistance. The voltage applied to the device under
test is adjustable from 50V to 5kV AC and 50V to 6kV DC.
programmable from 1uA to 20mA AC in 1uA steps and from 0.1uA to 5mA DC in 0.1uA steps.
The output voltage for Insulation Resistance tests is 50V to 1000V DC over a measurement
range of 100kΩ to 50GΩ.
Start-Up
The Sentry Plus Series unit can be operated from a power source between 90 and 250VAC at a
power line frequency of 50 or 60Hz. The standard Sentry Plus Series unit is shipped from
QuadTech with a 3.15A fuse in place for AC 90-130V operation. (A 1.6A fuse is included for
200-250V operation). The Sentry Plus unit is shipped with the line voltage selector set for 120V.
Refer to paragraph 1.4.3 for instructions on changing the fuse or line voltage selector.
Connect the Sentry Plus Series unit AC power cord to the source of proper voltage. Operate the
Sentry Plus Series instrument with its chassis connected to earth ground. The Sentry Plus
instrument is shipped with a three-prong power cord to provide this connection to ground. This
power cord should only be plugged into a receptacle that provides earth ground. Serious injury
may result if the Sentry Plus Series instrument is not connected to earth ground.
Press the [POWER] button on the front panel to apply power. To switch the power off, press the
[POWER] button again or if measurements are to be made proceed with the Test Parameter
Setup in Table COI-1. The Sentry Plus Series instrument should warm up for 15 minutes prior to
use.
Please read this instruction manual in its entirety before operating this instrument.
