The 7079 provides the following for the testing and calibration of electrical process loop signals.

0 to 199.99mA Measurement
To measure current connect the 7079 in series with the circuit under test. The display will now show the current flow in the circuit together with the polarity.

Continuity
To test for circuit continuity connect the circuit under test in series with the 7079 continuity terminals. If a circuit exists a audible and visual alarm will sound. The threshold for this test is approximately 100 ohms.

Output 24V
A separate isolated 24VDC supply is provide to enable the powering up of 4 - 20mA loops for the instrumentation under test. This output is overload protected with an auto re-settable fuse. In the event of an overload allow the fuse to cool for a few minutes before further use.

EasyCal
An RS232 port is provided for connection to an EasyCal control port. EasyCal can readback the loop current on demand to allow automatic calibration of pressure transmitters.
