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. 1 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. Frequency 50 Hz 60 Hz FAST* MEDIUM SLOW 3.3 ±1 ms (300) 130 ±5 ms (8) 1,040 ±50 ms (1) 3.3 ±1 ms (300) 108 ±5 ms (9) 1,080 ±50 ms (1) * Approximately 55 ms required for self-calibration at 30-minute intervals. Does not apply at resistances higher than 2MΩ, or LPΩ higher than 200kΩ (see page 5). 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. ■ Select from 3 types of units 3237 The basic and economical The high-accuracy & multi-functional ✓ DC V basic accuracy: ±0.01% rdg.±2dgt. ✓ Includes frequency measurement for AC and DC A 32 37 32 38 32 39 ✓ DC V basic accuracy: ±0.025% rdg.±2dgt.
