3237

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 high-

performance 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 high-

precision, 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.

For specifications, see pages 5 and 6.

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

■ Interface supports full remote operation

Measurement can be automated by using a controller to operate

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.
