Choice of the state of the relay associated led
The led indicates the alarm state.
Led lit when relay active (coil supplied)
Led still when relay active (coil supplied)
Hysteresis setting in display points .
The hysteresis is active on switching from lit led to still led; i.e.
on switching out of alarm, as the led represents the alarm state.

MESSx •• Display of alarm messages
A programmed alarm message can be made to appear alternating with
measure. The message will appear only during the alarm state, while the
associated led is lit.
•• Setting of setpoints : There are 2 ways to adjust setpoints.
- either in mode programming entering the correct access code
- or by pressing simultaneously on and if the access to quick
entering has been authorized during the code programming ( see p20 ).

•• Time delay on the alarm
The time delay on the relay si adjustable from 000.0 to 025.0s, in 0.1s
increases
It is active both on switching and switching back.
•• Alarm recording
Allows recording of the alarm after a setpoint has been passed. Once
measure reverts below the alarm setpoint, the relay remains on and the
led blinks to warn the user that a setpoint has been passed (to reset the
recording of alarms to zero see menu p21 ).
Note : Exit from mode programming wih configuration saving will reset
alarm recordings to zero.
Weight of the pulse to be applied on the totalizer unit
adjustable from -10 000 to +10 000.
eg. :
1 : one pulse at each increase of the totalizer unit
-1 : one pulse at each decrease of the totalizer unit
1000 : one pulse every 1000 increases of the totalizer unit
-1000 : one pulse every 1000 decreases of the totalizer unit
Pulse duration : 100ms, 200ms or 400ms.
Note : The programmed pulses duration applies both to the high and low
level, in order to allow some time between two consecutive pulses. When
the pulse frequency is too high in relation to the output capacity, they are
stored in a buffer, and restituted as soon as the frequency drops again. A
( SAVE, YES ), a totalizer zero reset or a power supply cut will reset the buf-
fers to zero.

•• Self-diagnosis :
The meter permanently watches any drifts that may surge on its compo-
nents. The self-diagnosis serves to warn the user in case of abnormal
increase of these drifts, before they provoque false measures.
The self-diagnosis error information can be reported :
· On the display : An error message appears alternating with measure;
an error code is registered and can be read in menu About
