The ergonomically designed Wahl C150 On-site Multifunction Calibrator includes a built-in “easy connect” terminals, portable and bench top flexibility and intuitive embedded software. The Wahl C-150 is fully protected with an external antishock rubber boot with IP 54 rating.
It also features five user-selectable languages, 0.005% accuracy over one year, NIST traceability and HART transmitter compatibility. An elastomer keypad protects the unit from dirt and grease. In addition its raised keys allow the unit to be used with gloves.
The battery offers eight hours of use, and the unit comes with six testing leads, a quick battery charger, CD instruction manual, heavy-duty carrying case, NIST Certification and one-year warranty.
C150 High Accuracy Portable Multifunction Calibrator
(C150 FUNCTIONS)
QUICK CONNECT SYSTEM: This unique system is easy to use by pressing down on the top of the terminal, and inserting bare wires with a diameter up to 3 mm (or 10AWG), or compensated thermocouple connectors, and then releasing.
Wires are held tight between 2 brass plates which provide thermal stability to create excellent cold junction compensation for thermocouples.
This system also allows 4mm banana plugs or safety plugs to be connected on the front panel.
DISPLAY RESOLUTION: C150 has user selectable resolution to allow measurements to meet specific testing requirements.
FUNCTIONS: The C150 allows the following physical values to be measured and simulated:
-
Voltage
-
Current
-
Resistance
-
Temperature by thermocouples, RTD and thermistors resistance
-
Pressure measurement when used with optional external pressure module. (Simulation requires user supplied pressure pump)
-
Frequency/counting from signal and dry contacts
HART PROTOCOL: works with HART Protocol instruments:
-
Connection of 1 to 15 analog sensors with 24V power supply
-
Compatibility with Protocols «HART 5» and «HART 6». Setting and configuration of these sensors through the C150
-
Loop supply with insertion of 250 ohm internal resistance
-
“Verify” HART menu option: Verification of the current loops and the detectors (manually or automatically). All the information is stored in the Verification report.
-
Loop current and detectors can be adjusted from the C150
-
HART Instrument status: Information about the response of the instrument during test can be dis- played: overload loop, out of limit variable.
CALIBRATION:
Sensor Calibration: Calibration coefficients can be implemented in order to correct sensors. C150 is able to generate calibration reports.
Electronic Devices Calibration: Calibration can be performed by comparison (2 probes and temperature source driven) or using signal generation. Two methods are available: manual or automatic, with uncertainty taken into account. Calibration set points are entered by user.
Transmitter Mode: The measured value is emitted as a 20mA or voltage signal to drive dry blocks and baths.
DISPLAY: C150’s dual display simultaneously displays the measurement value, the emitted value, the gauge and the used functions. On the top line, date, time and external temperature are indicated. During measuring, Average, Maximum, Minimum, and the number of measurements are displayed on the left. During emission, this part of screen displays all details of ramps, steps and constant value emission functions. Drop-down menus are used with the navigator.
