Improved Test Reliability
If a test lead wire were
to break during testing with
a tester that does not offer
contact check functionality,
defective test pieces would be
judged to be non-defective.

Contact check function improves test reliability
The 3174’s contact check function lets you
detect test lead
wire breaks and faulty
contact during testing by sensing
measurement issues in real time.
Withstanding voltage tester
Voltage output
Voltage monitor
The 3174 improves test
reliability by monitoring
voltage to detect lose
leads during testing
and faulty wiring during
measurement.
*Since contact check is performed
while testing is in progress, use of
contact check functionality does
not increase cycle time.

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

withstanding voltage followed by insulation resistance tests,
or press the I

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.)

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.
