The CAL599 is a low cost full featured reader and signal source for thermocouples and process signals.  It supports a wide variety of signals including thermocouples, millivolt, voltage and mA signals.

Thermocouples
The CAL599 supports J, K, T, E, R, S, N, B.  As a meter it can read the full temperature range of these thermocouples.  As a source output it will output a signal from 0°C to the upper range of the thermocouple.  When working with thermocouples you can select automatic cold junction compensation or manual compensation (the user sets the cold junction temperature).  Cold junction compensation may also be disabled.

Millivolt and Voltages
The CAL599 can read and source both millvolts and voltages.  As millivolt reader it can measure signals from -10 to 11 0mVdc and source 0 to 110 mVdc.  The voltage measurement range is -5 to 30 Vdc and the voltage source range is 0 to 11 Vdc.  The voltage output can be incremented or decremented by individual digit, or can be incremented in percent of full scale. You can also select waveform output in which the signal will ramp according to a preset waveform.

mA Current Signals
In the mA current mode the CAL599 has a range of 0-22mA.  It can measure current while providing 24Vdc loop power or without providing loop power.  The loop power is useful  when working with transmitters and other sensors which require power.  When sourcing current, the CAL599 can generate a current output or it can simulate a loop powered transmitter.  In the simulate mode the CAL599 can be  connected to a loop which already has power and it will regulate the current to the desired level.
