1. PRODUCT INTRODUCTION
1-1. Description
The GPT/GPI-700A series Electrical Safety Testers (EST) are
designed for AD/DC Withstanding Voltage test, Insulation Resistance test
(IR) and Ground Bond test (GB) in order to provide a safe and accurate
test environment for the operator. With thoughtful design described in
1-2. Feature insures a safe operation of high voltage test and protect user
from hazardous impact. Besides, the series can be used together with
scanner box of SHB-001-1 & SHB-001-2.
The Electrical Safety Testers comply with the requirement of the
electrical equipment & appliance control ordinances and JIS, CSA, UL,
BS and other overseas standards as well. The testers can be used for
withstanding voltage test of the various types of electrical and equipment
and components.
The GPT/GPI-700A series are based on the family of GW
withstanding voltage tester including AC Withstanding Voltage test, DC
Withstanding Voltage test, Insulation Resistance test and Ground Bond
test (GB).

1) No load setup of trip current and output voltage
A safe way to setup trip current and output voltage without high
voltage activated.
2) A large 24×2 character LCD with adjustable LED backlight
Provide a clear display about test parameters, which including
group, step, mode, status, output voltage, trip current and test
time.
3) Easily and quickly setup by front panel
A user-friendly interface provides user an easy and quick way to
set all parameters.
4) Electronic ramping and testing
Digital controlled ramping time and testing time.
