PROGRAMMING C
NTA47262-000A6 19 / 55
Setting AlarmsC.2.5
Alarms are validated by successively pressing this key. The unit displays one of the following:
Alarm 1 and the trigger direction.
Alarm 2 and the trigger direction.
Alarm 1 and Alarm 2 and their trigger directions.
These value and direction parameters are user programmable (see sub-section 3.4.5: "Managing an Alarm
Threshold").
The AL1 and AL2 LEDs light up when the respective programmed threshold values are reached.
Connecting to ConnectorsC.2.6
The measurement wires are connected using lockable cylindrical connectors.
Any drop in the voltage on the load terminals is measured between the two "voltage" (U) wires.
The current wires I can deliver a current level that varies from 1 mA to 10 A.

The DB9 connector is used to trigger remote measurements ("TRIG").
On the trigger test prod, the "READY" LED indicates that a measurement can be made.
The DB9 connector is used for RS232 communication with a PC or a printer.
The main connection pins used are:
A "Pt100" type thermometric resistor can be connected to the unit (using an extension cable if necessary) to
perform compensated measurements. The use of a temperature sensor listed in the Accessories section is
recommended.
