DIGITAL HiTESTER
3239 (4-terminal Ω function)
3238 (Advanced model)
3237 (Economically priced)
Field measuring instruments
Outstanding performance for production lines with a sampling rate of 3.3 ms
High-speed DMM
The DIGITAL HiTESTERs 3237, 3238, and 3239 can perform 3.3 ms high-speed sampling, and come
equipped with a comparator, external input and output, and an RS-232C interface. These three highperformance DMMs can be used not only in laboratories, but in production lines that require the minimal
tact time.
The 3237 is the basic model, and is equipped with the basic necessary functions. The 3238 is a highprecision, broadband model that also features current measurement terminals and a frequency measurement
function. The 3239 includes the functions of the 3238 plus the 4-terminal resistance measurement function.
All three units are designed with emphasis on measurement speed and safety.

3.3 ms/sample
High-speed Performance and Reliability
■ Features
Sampling speed Values in the ( ) show samples/second.
■ Samples at rates of up to 300 samples/sec. (3.3 ms/sample)
■ Comparator function provides high-speed pass/fail evaluation
■ Equipped with external input and output for sequence control
■ Usefull Save/Load function helps work go faster
The 3237, 3238 and 3239 are equipped with a variety of
functions that help minimize tact time in production lines.
For details, see page 2.
■ Low power resistance measurement function
prevents sample deterioration
The 3237, 3238 and 3239 use a low power Ω function to
minimize sample degradation when measuring resistance.
With this function, open terminal voltage never goes over 0.45
V DC, and measurement current never surpasses 100 µA DC.

For the 3238 and 3239's frequency function gate time, see page 5.
■ True RMS value measurement
Both the 3237 and 3238 use true RMS measurement
for determination of distorted waveforms. In fact, HIOKI
guarantees accuracy of the 3238 and 3239 for AC voltage of
10 Hz to 300 kHz, and AC current of 10 Hz to 30 kHz.
For specifications, see pages 5 and 6.
■ Interface supports full remote operation
Measurement can be automated by using a controller to operate
the 3237 or 3238 through the GP-IB or RS-232C interface.
For specifications, see pages 5 and 6.
For details, see page 3.

■ Supports large AC current measurement by clamp sensor
■ Easy setup
Both the 3237, 3238 and 3239 can measure live line currents using an
optional clamp sensor. Enter the name of the clamp sensor being used
and display current values simply by selecting a range.
Clamp sensor settings screen
Select 9010
Select the 20 A range.
From the menu's clamp sensor selection screen, select the name
of the sensor with the cursor key and press the
key.
Then, select the same range as you set for the sensor with the
cursor key.
* The accuracy of the clamp sensors shown on the left (when used with the
DMM) is calculated by taking: the difference in the AC V accuracy for the
DMM (dgt.) ✕ 10 (dgt.).
For the AC V accuracy of the DMM, see page 6.
In addition to the sensors described above, you can also connect the 3283, 3284, 3285 (requires the 9094) Clamp On HiTesters, and the 9277, 9278, 9279 (requires the 9555) DC Sensors.
