Chroma 19053 - Introduction; An Overview of Product; Features; Initial Inspection

Introduction
1. Introduction
1.1 An Overview of Product
Automatic withstand / insulation / grounding testers of the instrument are designed for
automatic withstand, insulation resistance, grounding resistance and short/open circuit
detection of electromechanical and electronic equipments.
The testing aspect of withstand voltage, the output power of the tester is AC: 150VA(5kV,
30mA), DC: 60VA(6kV, 10mA). Therefore, it is for withstand test of electronic and
electromechanical and component.
The testing aspect of insulation resistance, the measurement range of the tester is 0.1MΩ ∼
50GΩ and test voltage range is 50V ∼ 1000V can be set arbitrary.
In the testing aspect of short/open circuit detection, please test if test capacitance is short or
open before testing high voltage. Please make sure the DUT good contact then processes
high voltage test.
All of setting status, time, current, voltage, resistance value, memory number etc are listed on
the display, it is unnecessary to remember any parameter status which be set.
The tester is equipped with Good and No Good judgment machinery and signal output of
testing result and remote control. It is also for GPIB interface and RS232 interface of
automatic test system. The above equipments makes high efficient and accurate test.
1.2 Features
y AC / DC withstand voltage, insulation resistance test and short/open circuit detection four
in one model.
