DIGITAL M-ohm HiTESTER 3154

DIGITAL MΩ HiTESTER 3154
Safety Standards Measuring Instruments
For the Laboratory to the Production Line
Six Test Voltages from 25 to 1000 V
The Model 3154 DIGITAL MΩ HiTESTER provides six selectable
test voltages: 25, 50, 100, 250, 500 and 1000 V, in order to support a
wide variety of tests to evaluate electrical and electronic components
and equipment. Comparator and timer functions facilitate easy
insulation resistance testing in accordance with various safety
standards, and a complete external I/O interface is provided for
efficient automated line testing.
1
Efficient Insulation Resistance Testing
✱ Insulation testing of electrical and electronic equipment
Motors, printers, magnetic heads, etc.
✱ Insulation testing of electrical and electronic components
Transformers, coils, switches, relays, etc.
✱ Insulation resistance testing according
to various standards
Machinery, medical equipment, home appliances, office equipment, etc.
✱ High voltage resistance testing
Resistance measurements of components in actual operating circuits.
●Six Measurement Voltages Provided in a
Single Unit
Any of six measurement voltages can be selected for
use in a wide range of applications, from electrical
and electronic component testing to electrical and
electronic equipment. The comparator can be set up
for use with each measurement voltage.
●Storage for Ten Setting States
Up to ten setting states can be stored for quick
selection when testing for compliance with various
standards.
●Easy Standards Testing
Testing for compliance with various safety standards is
simplified by using the comparator and timer functions
for quick pass-fail judgment of minimum acceptable
limits.
●Automatic Electrical Discharge Function
The unit discharges any charge buildup on the measured
object as a result of electrical loading. This electrical
discharge function prevents the effects of one test from
being carried over to a subsequent procedure.
●Remote Control
Operations such as test start/stop and voltage selection
can be controlled remotely, such as for start/stop control
from a switching probe.
●Slow Sampling Selection to Minimize Instability
Selectable fast (10 sample/s) and slow (1 sample/s)
sampling rates are provided. Slow sampling minimizes
instability when measuring at highly reactive test points.

Full Support for Automatic Operation
Both external I/O and RS-232C interfaces are provided
to support fully automated operation. Measurement
values can be tracked and recorded from the analog
output, and printing is supported on an external printer
using RS-232C.
●Record Variations using Analog Output
This unit provides two types of analog output. Measurements are
output linearly as voltages between 0 and +4 V DC, and insulation
resistance fluctuations can be recorded.
1. Outputs each measurement range.
2. The maximum measurement
range for each measured voltage
is output between
0 and +4 V DC.
