DIGITAL HiTESTER 3239 (4-terminal 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.

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.
Does not apply at resistances higher than 2M, or LP higher than 200k (see page 5). For the 3238 and 3239's frequency function gate time, see page 5.
* Approximately 55 ms required for self-calibration at 30-minute intervals.
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.
Low power resistance measurement function prevents sample deterioration
The 3237, 3238 and 3239 use a low power 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 A DC.
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.
