  • Description

    The precision calibration unit combines high accuracy, low drift, low noise and superior long-term stability with multiple functionality and simple operation. Ramps, Δ+/Δ-, and multiple setpoint storage make the operation of the device easier for the user.

    For that reason the application possibilities are many:

    • Calibration of current and DC-voltage meters
    • Precise testing of thermocouple temperature measuring instruments
    • Calibration of controllers, sensors, detection devices and other devices used in process control
    • Open-loop process control with the aid of integrated ramp function

    DIGISTANT® model 4462 can be used both as a standalone table-top device, as well as in automatic, computerassisted manufacturing and testing systems.

    It is possible to set currents of ± 200 nA ... ± 52 mA, voltages of ± 1 μV ... ± 30 V and, optionally temperature setpoint values of 14 thermocouple types.

    The output value is fed back via the sensor line to eliminate voltage drops across the measuring leads. The device has an adjustable current/voltage limitation. An external voltage divider of 1 up to 1:1000 can be considered internally.

    With the thermovoltage sourcing option you can enter °C, °F and K, the temperature scales ITS 90 or IPTS 68 and the comparison point mode constant/external. Furthermore, when sourcing thermocouples a calibrated external comparison point can be used, whereby the data for calibration in the device can be taken into consideration.

    Indication of the source value is carried out in large 12 mm figures on an illuminated graphics-LCD.

    The device can be operated both via the keyboard as well as the interface.
