The JOFRA mAcal mA loop calibrator generates and measures the current in the loop on 2-wire transmitters including 24 VDC loop supply. The built-in functions contribute to control time saving, process optimization, safe measurements and reduced costs.
Split loop calibration. Each component of the process measurement and control loop is calibrated as an independent item. The transmitter can be calibrated using a precision JOFRA signal calibrator. The indicator or controller can be calibrated either as described for the transmitter or by using the mAcal loop calibrator which simulates an output of 4-20 mA proportional to the temperature (or pressure). The sensor part can be brought to the workshop for a timesaving automatic calibration.

The CSC line of signal calibrators are dedicated units designed to make your calibration and maintenance tasks easier to perform. The JOFRA CSC100 is engineered for instrument loop calibrations and is specifically manufactured for 4 to 20 mA loops; however this versatile instrument offers much more than that.
This calibrator can source and read current and voltage; including millivolts. It can also be used as a signal simulator to test your transmitters without the need for actual operation.
The CSC100 also offers features such as an auto-stepping function, an isolated read-back circuit, and fuse-less protection. These handy time savers are combined in a package offering with an easy-to-read, two line display and an intuitive keypad with a knob for fine adjustments.
This calibrator is more than a simple tool but it is as easy to use as any device that you have in your toolbox. The CSC100 signal calibrator offers you the accuracy and features that you need in a convenient, compact, and easy to use package.

The CSC line of signal calibrators are dedicated units designed to make your calibration and maintenance tasks easier to perform. The JOFRA CSC200 is engineered for the calibration of temperature instruments offering the ability to measure and simulate several different types of RTDs and TCs. This instrument makes the job easy by utilizing a thermocouple plug for easy connection and can work with 2, 3, or 4 wire RTDs.
The CSC200 also offers features such as user defined setpoints with a recall function, selectable cold junction compensation, and installed curves for 14 RTD and 13 TC types. These handy time savers are combined in a package offering an easy-to-read, two line display and an intuitive keypad with a knob for fine adjustments.

The ASC300 is substantial enough to cover all your needs for a process signal calibrator with superior accuracy and compact enough to fit into your tool box and operate with one hand for easy field calibration. The ASC300 can change your entire calibration regimen for signal, pressure, and temperature. You can combine this versatile calibrator with the JOFRA APM external pressure modules or a JOFRA dry-block calibrator to meet your calibration needs.
The JOFRA ASC300 offers simultaneous input and output. This means that you can calibrate and adjust a temperature transmitter on the table with no other necessary instruments.Output the sensor signal and input the mA from the transmitter. If you select mA Loop the JOFRA ASC300 will also supply the 24 VDC for the loop. In the display you will see both your output temperature and the return mA from the transmitter. Enter the zero and full scale values and you can make quick 25% steps or go direct to zero or full span values. The JOFRA ASC300 has dedicated keys for this operation so adjustment on the transmitter is made easier.
