4. READING THE %MC VALUE
Press the “READ” key. Within 1 or 2 seconds, the meter will display the %MC between 8.0 and 37.0.
The meter will automatically correct the reading for the sample temperature. The reading will be
displayed for 2 seconds and if the “READ” key is still pressed, then the cycle will be repeated. The
buzzer will sound if the displayed reading is above the set point value entered in the meter (default is
20.0).
The meter will “store” the reading, provided that the user releases the “READ” key, otherwise the
meter will initiate another “READ” cycle without “storing” the previous reading. This feature lets the
user take a number of readings in sequence and only “keep” the readings of his choice.
When the “READ” key is released, the meter will add the last displayed value to the sum of the
previous readings (up to 100), provided the value is within the range. When all the 100 readings are
taken, the meter will automatically display their average before turning off. No new value will be added
to the sum unless the user erases the readings.
NOTE: The reading below 8.0% will be displayed as “.0” and above 37.0% as “99.9”.
These are not considered valid readings and will not be stored.
5. CHECKING THE AVERAGE AND MAXIMUM VALUE OF THE ACCUMLATED READINGS
(And erasing them)
As mentioned before, the meter adds the value of the new reading (provided that the “READ” key is
released) to the sum of the previous readings. The meter holds this sum, as well as the number of
readings added so far and the HIGHEST reading. Up to 100 readings can be accumulated. After that,
the meter will stop adding the new reading and display the average every time a new reading is taken
to remind the user to erase the readings to start accumulating the new ones.
At any time, the user can check the AVERAGE of the accumulated readings by pressing the “CHECK”
key. The meter will display the number of readings accumulated for one second, followed by the
AVERAGE value (displayed as “A xx.x”) for two seconds and the MAXIMUM value for another two
seconds. If at the end of the total period, the meter finds the “CHECK” key pressed, it will erase the
accumulated readings. Hence, the user must release the key before four seconds if he wants to retain
the readings. However, if all 100 readings are accumulated, then he should keep the key pressed to
erase the readings so that the meter can accumulate the new ones.
6. TO CHECK THE METER CALIBRATION
To check the meter calibration, the user must PRESS first the “READ” key, immediately followed
(within one second) by the “CHECK” key. The meter should display “12.0” +/- 0.2. Since a relay
disconnects the external input when checking calibration, there is no need to disconnect the external
electrode.
