Limit 1 y Limit 2.
Selection of the functioning val-
ues of the corresponding relays.
Input "ON" (closed contact).
Output "OFF" (open contact).
Selectable values between
± 1500 mV.
Output current.
Selection of mV values corre-
sponding to 4 mA and 20 mA.
Selectable values between
± 1500 mV.
Hold. Selection of the current
output when the instrument is in
Hold state: fixed at 21 mA or at
the mA corresponding to the last
measured value.
Language.
Selection of the working language:
English, Spanish, Italian or French.
Note: When programming, the
instrument is in hold state:
•
The contact relays are open.
•
The current output is frozen at
21 mA.
To quit the hold state it is neces-
sary to return to MEASURE.
The output current and relays will
activated after 10 s.
