Safety Precautions
WARNING
The Sentry Plus Series Hipot Tester can provide an output voltage as high as 6000V DC (5000V
AC) to the external device under test (DUT). Although the Sentry Plus 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.
1. The Sentry Plus unit is designed for operation with its chassis connected to earth ground.
The instrument is shipped with a three-prong power cord to provide this connection to
ground. This power cord should only be plugged in to a receptacle that provides earth
ground. Serious injury can result if the Sentry Plus is not connected to earth ground.
2. Tightly connect cable(s) to the (blue) RTN/LOW 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 DANGER light is ON.
5. Before turning on the Sentry Plus unit, make sure there is no device (DUT) or fixture
connected to the test leads.
6. After each test, press the [STOP] (red) button for safety if there is any concern that HV
may still be applied to the output terminals.
7. When the red DANGER LED is lit or flashing, NEVER touch the device under test, the
lead wires or the output terminals.
8. Before touching the test lead wires or output terminals make sure:
a) The red [STOP] button has been pressed
b) The red DANGER LED is OFF.
9. In the case of an emergency, turn OFF the POWER switch using a “hot stick” and
disconnect the AC power cord from the wall. DO NOT TOUCH THE Sentry Plus
INSTRUMENT.
10. If the DANGER LED does not go off when the [STOP] button is pressed, immediately
stop using the tester. It is possible that the output voltage is still being delivered
regardless of the TEST ON/OFF control signal.
11. When the Sentry Plus instrument is used in remote control mode, be extremely careful.
The High Voltage Output is being turned on and off with an external signal.

Condensed Operating Instructions
WARNING
High Voltage is applied to the white HV Output Terminal anytime the red DANGER LED is ON
or flashing. Always make sure the DANGER LED is OFF when connecting or disconnecting
the device under test (DUT).
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. The trip current limit is
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 100kΩto 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.
NOTE
Please read this instruction manual in its entirety before operating this instrument.
These condensed operating instructions are not a substitute for all the information provided in the
remainder of this manual.
NOTE
Refer to paragraphs 2.3 through 2.9 for a full description of programming test parameters and
instruction on how to store the test setup. Test parameters must be set before the Sentry Plus
Series instrument can be zeroed.

Offset
After setting your test parameters, zero the Sentry Plus Series instrument by using the automatic
offset. With no device connected, connect the appropriate cable (or other fixture) into the
OUTPUT connectors. Refer to paragraph 2.13 cable connections based on test to be performed.
Return and HV test leads should not be connected together (open circuit) for AC and DC hipot
tests. Return and GC test leads should be connected (short circuit) for a GC test. There is no
offset in an IR test.
NOTE:
If Ground Continuity (GC) is turned ON when performing an offset, the continuity lead must be connected to the
return (RTN/LOW) terminal, otherwise turn the continuity test OFF.
Prior to performing the OFFSET function:
•Allow the instrument to warm up for 15 minutes.
•Connect the Test cables (or fixture) to the front panel OUTPUT and RTN/LOW connectors.
•Program the test steps.
With the instrument in STAND BY status:
•Press [F4] = MORE
•Press [F3] = OFFSET
•Follow instructions on display: i.e.: connect OPEN across OUTPUT terminal.
•Press green [START] button.
•Wait while instrument gets OFFSET value.
•The OFST block at the bottom of the display is now highlighted (back lit).
•Press [F4] = MORE to return to STAND BY status.
