COn Group - worked time count
[67] Co.tY – Measurement type
Available:
Always.
Range:
oFF = Not used
dAY = Total worked days with threshold. It is the
number of hours that the instrument is
turned ON divided for 24.
Hour = Total worked hours with threshold. It is
the number of hours that the instrument is
turned ON.
Note:
It is an internal counter for machine service inspection
intervals. It works every time the instrument is turned ON.
When the count reaches the programmed threshold, the
display shows alternately the standard display and the
message “r. iSP” (requested Inspection). The count reset
can be done only by changing the threshold value.
[68] h.Job – Threshold of the working period
Available:
When [67] Co.tY = tot.d or [67] Co.tY = tot.H
Range:
oFF = threshold not used
from 1 to 999 days or
from 1 to 999 hours.

CAL group - user calibration group
This function allows to calibrate the complete measuring
chain and to compensate the errors due to:
–
Sensor location;
–
Sensor class (sensor errors);
–
Instrument accuracy.
[69] AL.P – Adjust Low Point
Available:
Always.
Range:
from -1999 to (AH.P - 10) (E.U.)
Note:
The minimum differance between AL.P and AH.P is
equal to 10 Engineering Units.
[70] ALo – Adjust Low Offset
Available:
Always.
Range:
From -300 to 300 (E.U.).
[71] AH.P – Adjust High Point
Available:
Always.
Range:
From (AL.P + 10) to 9999 (E.U.)
Note:
the minimum differance between AL.P and AH.P is
equal to 10 Engineering Units.
[72] AL.o – Adjust Low Offset
Available:
Always.
Range:
From -300 to 300 (E.U.).
Example:
Environmental chamber with an operative range
from 10 to + 100 °C.
1.
Insert in the chamber a reference sensor connected with
a reference instrument (usually a calibrator).
2.
Start the control of the instrument, and set a set point equal
to the minimum value of the operative range (e.g. 10°C).
When the temperature in the chamber is steady, take note
of the themperature measured by the reference system
(e.g. 9°C).
3.
Set [130] AL.P = 10 (low working point) and [131] ALo = -1
(it is the difference between the reading of the instrument
and the reading of the reference system).
Note that after this set the measured value of the instrument
is equal to the measured value of the reference system.
4.
Set a set point equal to the maximum value of the ope-
rative range (e.g. 100 °C). When the temperature in the
chamber is steady, take note of the themperature measu-
red by the reference system (e.g. 98 °C).
5.
Set [132] AH.P = 100 (low working point) and
[133] ALo = +2 (it is the difference between the reading of
the instruent and the reading of the reference system).
Note that after this set the measured value of the instrument
is equal to the measured value of the reference system.

The most important step of the configuration procedure is
completed.
In order to exit from configuration parameter procedure,
proceed as follows:
–
Push
button.
–
Push
button for more than 10 seconds.
–
The instrument will come back to the “standard display”.
