Description
The Wahl C75 Calibrator integrates all the necessary functions for calibration and maintenance of processes, making it an ideal instrument for maintenance, quality control, and calibration. With ergonomic design and embedded software, the C75 is an easy-to-use, high performance calibrator.
The C75 is capable of simultaneously measuring and generating voltage, current, frequency, resistance signals, resistive probes, and thermocouples - on two isolated channels. Wide, high contrast backlit display is excellent for use in low ambient light conditions.
Add the optional absolute or relative external pressure modules (sold separately) to add pressure to your list of measurements. Optional external pressure modules are digital and connected through a RS485 cable to the digital input corrector. All data is digital. Measurements are compensated in temperature due to a polynomial correction implemented into the EEPROM at the factory.
Record data automatically or on user request. 10,000 data can be stored and displayed on the screen as a curve or list.
The unit is rated IP54 and protected by an anti-shock boot. Polycarbonate keypad protects the unit from dirt and grease, and the raised keys allow the C75 to be easily used while wearing gloves. Ten user programmable configurations are available for use with repetitive jobs.
Unique quick connect system is easy to use; simply press down on the top of the terminal and insert bare wires (up to 3 millimeters or 10 AWG) or compensated thermocouple connectors. When releasing the terminal, wires are held tightly between two brass plates for thermal stability, creating excellent cold junction compensation for thermocouples. This systems also allows for the use of 4 millimeter banana plugs or safety plugs to be connected to the front panel.
The C75 allows the following physical values to be measured and simulated:
- Voltage
- Current
- Resistance
- Temperature, via resistive probes and thermocouples
- Pressure measurement when used with optional external pressure module. Pressure simulation requires user supplied pressure pump.
These functions allow scaling of process signals and corrections to temperature probes. The C75 is compatible with HART transmitters by inserting a 250 ohms resistance, allowing uninterrupted data transfer. Data can be stored and sent to PC for analysis.
The dual display simultaneously shows measurement value, emitted value, gauges, and used functions.
Selectable resolution allows the user to adjust in order to meet specific testing requirements. The top line displays date, time, and external temperature. While measuring average, maximum, minimum, and the number of measurements are shown on the left of the screen. During emission the left of the screen will display ramps, steps, and constant value emission functions. Access drop-down menus using the navigator.
