Unpacking and Inspection

Inspect the shipping carton before opening. If damaged, contact the carrier agent immediately.
Inspect the Sentry Plus Series instrument for any damage. If the instrument appears damaged or
fails to meet specifications notify QuadTech (refer to instruction manual front cover) or its local
representative. Retain the original shipping carton and packing material for future use such as
returning the instrument for recalibration or service.

Product Overview

The Sentry Plus Series is available in three models, the 10, 20 and 30, all of which provide AC
Hipot testing capability. Additionally, the Sentry 20 & 30 Plus instruments provide DC Hipot
testing. The Sentry 30 Plus unit provides Insulation Resistance testing. The hipot test can be
programmed over a voltage range of 0.05 to 5kV AC and 0.05 to 6kV DC with a min/max
leakage current detection range of 0.001 to 20mA AC and 0.0001 to 5mA DC. Insulation
resistance measurements are possible to 50GΩ at programmable DC test voltages between 50
and 1000V. Each instrument comes standard with programmable ground continuity, internal
storage containing 60 memory locations (10 steps each) and a remote interface with start/stop
inputs & pass/fail outputs.

UL Requirements
The Sentry Plus Series instruments meet the requirements outlined by UL for Hipot Testers. The
Sentry Plus indicates the test potential (test voltage), has both visual and audible indication of
failure and the STOP switch must be manually pressed prior to another measurement being
made. The Sentry Plus Series instrument has a 100VA output [(5000V * 20mA) = 100VA]. The
Sentry Plus Series instrument also measures and displays the output voltage directly at the output
terminals during the test.
