factory reset - default parameters loading procedure
Sometime, e.g. when you re-configure an instrument previously used for other works or from other people or
when you have made too many errors during configuration and you decided to re-configure the instrument, it
is possible to restore the factory configuration.
This action allows to put the instrument in a defined condition (the same it was at the first power ON).
The default data are those typical values loaded in the instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1. Press the
button for more than 5 seconds. The upper display will show
PASS
while the lower display
shows
0
;
2. using
and
buttons set the value
-481
;
3. Push
button;
4. The instrument will turn Off all Leds for a few seconds, then the upper display will show
dFLt
(default) and
then all Leds are turned ON for 2 seconds. at this point the instrument restarts as for a new power ON.
The procedure is complete.

6. errOr MeSSaGeS
Out of range signals
The instrument points out, on the upper display, the OVer-raNGe and uNder-raNGe conditions using the fol-
lowing indications:
Over-range
under-range
The sensor break will be signalled as an out of range:
Note: When an over-range or an under-range is detected, the alarms operate as in presence of the maximum
or the minimum measurable value respectively.
To check the out of span error condition, proceed as follows:
1. check the input signal source and the connecting line.
2. Make sure that the input signal is in accordance with the instrument configuration.
Otherwise, modify the input configuration (see section 4).
3. If no error is detected, send the instrument to your supplier to be checked.
List of possible errors
eraT fast auto-tune cannot start. The measure value is too close to the set point.
Push the
button in order to delete the error message.
ouLd Overload on output 4. The message shows that a short circuit is present on Out 4 when it is used as ou-
tput or transmitter power supply. When the short circuit disappears the output restarts to operate.
Noat auto-tune not finished within 12 hours.
ereP Possible problem in the instrument memory. The message should automatically disappear, if the error
persists, send the instrument to your supplier.
rone Possible problem of the firmware memory. If this error is detected, send the instrument to your supplier.
errt Possible problem of the calibration memory. If this error is detected, send the instrument to your supplier.
