7.3 The lower menu
In the lower menu for configuration and calibration the
following functions can be selected:
UNIT1, UNIT2, Time, Date, AutoOff,
CAL 1, CAL 2, CAL2L, CAL2H and
oil parameter: C1, C2, C3, C4
Selection with , the selected
function flashes and is entered
with . An entered function is
displayed steady.
The menu can be interrupted with
or by not pressing the thumb
wheel for 20 seconds.
UNIT1 (FOR SENSOR 1):
UNIT1 (default temperature) enables the selection of
different units for the first sensor channel. The selected
unit flashes and is activated using .
Units can be selected using and . Available
temperature units are °C or °F.
UNIT2 (FOR SENSOR 2):
UNIT2 (default humidity % RH) enables the selection
of different units for the second sensor channel.
The selected unit flashes and is activated using .
Units can be selected using and . Available
saturation units are % or PPM.
Time: Set time. Hours and minutes are
input in sequence.
Selection can be made using and
enter with .
Date: Set date. Day, month and year are
input in sequence.
Selection can be made using and
enter with .
Auto-Off: The time in minutes for
automatic switch off is set with Auto-Off.
If OFF (<1) is set, the device does not
switch off automatically.
Select with and ; enter with .
7.4 Calibration
There are two methods of % saturation calibration. One
point calibration is used more as a quick verification
where only one humidity standard is available. For
accuracy it is recommended that a two point calibration
is always performed
7.4.1 Temperature calibration
Important: Calibration should only be carried out by
skilled personnel using suitable calibration standards.
CAL1:
CAL1 initiates the one
point calibration for temperature.
The symbols for Sensor 1 and
Sensor 2 disappear from the
display. The actual value for
temperature is now displayed in
the upper half of the display.
The offset value for temperature
flashes in the lower area; this
value can be incremented using
and decremented using .
The temperature offset can be
adjusted ±10 °C (±18 °F) in steps
of 0.1 °C.
The offset value is confirmed
with .
The menu is than exited automatically and CAL
END is displayed.
Incorrect calibration is indicated by CAL FAIL and
must be repeated.
The factory settings can be restored by setting
the offset to 0.0.
7.4.2 One point calibration for % Saturation
CAL2: CAL2 initiates the
one point calibration for
humidity % RH.
The symbols for Sensor 1
and Sensor 2 disappear
from the display.
The actual value for
humidity is now displayed
in the lower half of the
display. The offset value
for humidity flashes in the
upper area; this value can
be incremented using
and decremented using
. The % saturation
offset value can be
adjusted a maximum
±10 % S in 0.1 % S
steps. The offset value is
confirmed with .
The menu is than exited automatically and CAL
END is displayed.
Incorrect calibration is indicated by CAL FAIL and
must be repeated.
The factory settings can be restored by setting
the offset to 0.0.
The calibration point should be in the range
11...95 % S (recommended 80 %).
For % saturation, setting the offset changes the
angle of the characteristic with zero as centre
point.
