1. GETING STARTED
This chapter describes the safety tester in a nutshell, including its main features
and front / rear panel introduction. After going through the overview, please read
the safety considerations in the Set Up chapter.
1.1 STW-9000 Series Overview
The STW-9000 Series Safety Testers are AC/DC withstanding voltage, insulation
resistance and ground bond safety testers.
The STW-9901/9801 are AC withstanding voltage testers, the STW-9902/9802 are
AC/DC withstanding voltage testers and the STW-9903/9803 are AC/DC
withstanding voltage and insulation resistance testers. The STW-9904 includes all
the test functions of the other models as well as ground bond testing. All models
can operate at up to 5kVAC for AC withstanding voltage testing and at up to 6kVDC
for DC withstanding voltage testing (excluding the STW-9901/9801).
For the STW-9000 models, the testing terminals are also mirrored on the rear panel
for added safety and for more permanent safety testing environments. They also
include an innovative sweep function to view test results as a graph.
The STW-9000 Series can store up to 100 manual tests, as well as run up to 16
manual tests sequentially as an automatic test, allowing the safety testers to
accommodate any number of safety standards, including IEC, EN, UL, CSA, GB,
JIS and others.
Note: Throughout this user manual, the terms ACW, DCW, IR and GB refer to AC
Withstanding, DC Withstanding, Insulation Resistance and Ground Bond testing,
respectively.
