Continuous full-auto withstanding voltage and insulation resistance testing
The 3174 lets you
set independent test conditions including
test voltage for withstanding voltage and insulation
resistance testing,
and you can perform these tests
continuously. Press the W
→
I key to automatically perform
withstanding voltage followed by insulation resistance tests,
or press the I
→
W key to automatically perform insulation
resistance followed by withstanding voltage tests.

Interlock function
Signal input from an external device such as an automatic
tester can be used to disable output and prevent testing,
ensuring safety during automatic testing and other uses.
GP-IB (option)
Enables remote control.
Contact check
LOW: A break in the lead is determined to have
occurred when the check current is not detected.
HIGH: A break in the lead is determined
to have occurred when the contact check
measurement voltage falls outside the range
defined by the upper and lower thresholds.
(Connectors are locked in place as shown
on the left to prevent the leads from
being disconnected.)
*Requires an additional pair of
9615 HIGH-VOLTAGE TEST LEADS.
Power cord inlet
Rear panel voltage output terminals
Status out relay terminals
Maximum input voltage: AC 150 V, DC 30 V
Maximum contact current: 0.5 A
The rear panel terminals are connected
at all times to the front terminals. When
embedding the 3174 HiTESTER inside
an automatic tester, connections can be
made via the rear panel terminals.
An OR operation applied to various enabled conditions
determines whether relay terminal output is turned on. Devices
such as the 9616 WARNING LAMP can be connected.
