Safety Standards

Measuring Instruments

Featuring contact check functionality

The effects of test lead wire breaks, erroneous test results caused by faulty contact, and

fluctuations in test voltage caused by variations in the instrument’s supply voltage on

withstanding voltage and insulation resistance testing are well known.

The 3174 (3174-01) AC AUTOMATIC INSULATION/WITHSTANDING HiTESTER is a

low-cost solution featuring contact check functionality as well as a stabilized power supply

to prevent the reduced test reliability that can result from these issues.

To streamline production line test processes, the HiTESTER also features configuration of

test parameters via RS-232C (GP-IB) and reading of parameters from the EXT I/O interface.

Improved Test Reliability

NEW

●

Contact check function improves 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.

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.

The ramp-up initial value, ramp-up and ramp-down time

parameters can be set independently.

The ability to obtain a judgment even after a forced stop increases testing freedom.

● True effective value display

Continuous full-auto withstanding voltage and insulation resistance testing

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.

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.

GP-IB (option)

Enables remote control.

RS-232C

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.)

Rear panel voltage output terminals

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.
