Check to make sure the Red Voltage Selector Switches on the rear panel agree with the power
source available. Depending on the power source the switch positions should be in the up or
down positions as shown in Figure 1-5 (Close-Up of Sentry Plus Series Rear Panel).
WARNING
NEVER TOUCH THE TEST LEADS IN ANY MANNER (this includes insulation on all wires and clips) when
HIGH VOLTAGE IS APPLIED and red DANGER LED is ON.
USE ALL PRECAUTIONS NECESSARY TO AVOID TOUCHING THE DEVICE UNDER TEST WHEN THE
RED DANGER LED IS ON OR FLASHING.
Connect the instrument power cord to the source of proper voltage. The instrument is to be
used only with three-wire grounded outlets.
Power is applied to the Sentry Plus Series instrument by pressing the green [POWER] switch on
the front panel to the ON (1 position). The Sentry Plus Series unit should warm up for a period
of at least 15 minutes prior to use.
WARNING
DO NOT TURN INSTRUMENT POWER ON OR OFF WITH TEST DEVICES CONNECTED.
2.3 Programming Electrical Safety Tests
The Sentry Plus Series instrument is capable of performing the tests listed in Table 2-2. A
single-step test can be performed on a device and is programmed as described in paragraphs 2.4
– 2.8. When the device under test requires a multi-step test the order of test precedence is
important. Refer to paragraph 2.9 for test setup store/recall instructions and to paragraph 2.10 for
instructions on programming a multi-step test.
