7 Operating manual – Material moisture measuring device T660 EN
Material settings
Here you can select the construction material for the measure-
ment. The following options are available:
• 0 no: No material selected.
• 1 An: The selected material is anhydrite screed.
• 2 Ce: The selected material is cementitious screed.
Please note that in case of the settings 1 and 2 an additional value
will be indicated in the upper measurement value display (14).
It is a combination of the material (1 or 2) and the calculated per-
centage.
• Example: 2_7.5 (7.5 % with cementitious screed).
1. Select MAT (17) whilst in configuration mode.
2. Press the OK button (10).
3. Select the desired value by use of the Up (7) or Down (9) key.
4. Press the OK button (10) for approx. 2 seconds.
– The device switches to measuring mode.
– With either setting 1 or 2 the indication MAT (17) continues
to be displayed.
Setting the offset
By use of CAL a single-point calibration can be carried out for the
selected sensor indications. All sensors are already factory-cali-
brated and have a corresponding characteristic calibration curve.
By stating a calibration value (offset) a global shift of the calibra-
tion curve, which has an effect on the entire measuring range, is
performed for the single-point calibration! The offset value to be
entered is that value by which the calibration curve will be shifted.
Example:
The displayed value is always 5 too high => change the offset
value for this measurement channel to -5.
The offset value's default setting is 0.0.
Changing the offset value brings about an automatic reset of the
measured values.
1. Select CAL (17) whilst in configuration mode.
2. Press the OK button (10).
3. Press the keys Left/menu (11) or Right/back (8) to select a
digit.
– The selected digit flashes.
4. Press the Up (7) or Down (9) key to change the value of the
selected digit.
5. Repeat the steps 5. and 6. until the value is set as desired.
6. Press the OK button (10) for approx. 2 seconds.
– The offset is set.
– The device switches to measuring mode.
– With set offset value the indication CAL (17) continues to be
displayed.
Exiting configuration mode
Configuration mode will automatically be terminated after 8 sec-
onds without entry.
You can quit configuration mode yourself anytime. Please note
that in such an event no changes made to the settings will be
adopted.
1. Press the Right/back key (8) for approx. 2 seconds.
– Configuration mode will be terminated.
Measuring mode
In the lower measurement value display (16) the measured value
is indicated in digits. In the upper measurement value display (14)
the measured value is indicated in % (mass-%) or %CM –
depending on the chosen setting.
1. Press the keys Right/back (8) or Left/menu (9) until the de-
sired measuring mode is displayed.
The device comes with the following measuring modes:
Holding the measured value
1. Set the measuring mode to HOLD.
– The current measured value will be held and displayed.
– The device will hold this value until the measured values
are set back or the device is switched off.
Resetting the measured values
1. Press the OK button (10) for approx. 2 seconds.
– All previously stored measured values of the measuring
modes AVG, MIN, MAX and HOLD will be set back.
– All measured values are then determined anew based on
the measurement proceeding in the background.
