Time Electronics 7061 - Multifunction Process Calibrator Module
The 7061 process calibrator module combines the essential functions of measurement and simulation of volts, millivolts, milliamps, and ohms with the direct readout simulation of thermocouples and RTD's in °C or °F units. Input and output functions are displayed simultaneously and the switch controls allow for easy and precise operation.
Five calibration points are instantaneously accessible through a preset percentage selector and all functions may be generated in a fully programmable ramp format.
In addition to the standard calibration facilities the module may be used as a signal converter. Any electronic input signal can be converted and output as a proportional signal of 4-20mA, 0-5V or sq. root 4-20mA.
The 7061 is highly adaptable, IPT 68 and ITS 90 curves are accommodated and non-standard thermocouples and RTD's may be programmed on request.
