599.0.000.0003.0	PC-Software LR-Cal AQ2sp incl. RS232-interface lead Temperatur sensor calibration: Automatic calibration routine for all type of temperature sensors with advanced features such reference sensor stabilization, time-calibration data are automatically populated and stored for printing report. This procedure can also be ran in manual mode to allow the operator to manually enter the data. This is particular useful when calibrating temperature device such as digital thermometer or analogue thermometers. Stress test: Simply set MAX and MIN value and the software will run an automatic stress test on single sensor or a batch. Advance thermostat calibration: Simply set the open and close temperature limits, type of thermostat, typ of test and the software will automatically run the test.

Note:
Datasheet and Manual can be downloaded as PDF files. To open PDF files, you need the ADOBE READER. You can get this software free of charge from ADOBE.

NOTE:
Indicated temperature ranges are valid at ambiemt temperature +20°C. The stated accuracy is based on ambient temperature +23°C and is guaranteed for 1 year.

To increase the measurement accuracy of the calibrator significantly, we recommend the -2I version of the temperature calibrator (with two measuring inputs) and the external high accurate reference probe LR-Cal LRT F.
