CHECK CALIBRATION
Remove the probe from the top of the meter.
Press and hold the read button (#1) and check button (#2) simultaneously. Meter is in
calibration if it displays “12” (± .2) on the scale, regardless of the scale setting.
If you check the calibration and the display does not read “12,” it is likely an indication of a
low battery. If this occurs, change the battery immediately. Continued use with a low
battery may cause the meter to go out of calibration. If you have a fresh battery and the
instrument still does not indicate an acceptable calibration, return it to DELMHORST for
service. See “Service for Your Meter” section.
CHANGE THE SET-POINT
To change the set-point value, press the set-point button (#4). The meter will
display the current set-point value.
To scroll forward to a higher value, hold the set-point button (#4) while the current
value is displayed and scroll to the set-point value desired.
To scroll backward through the set-point values, press and release the set-point
button (# 4). Within one second press and hold the set point decrease button (#3).
Continue to hold the set point decrease button (#3) and the set-point will decrease.
When scrolling in either direction, release the button to stop at your desired set-
point.
If the meter reads a %MC higher than that of the set-point, a buzzer will sound.
TO CHECK THE ACCUMULATED READINGS
This feature allows you to view the total number of all accumulated readings for the given
product you have chosen, the average of those readings, and the highest stored reading.
To add a reading to the sum of all previously stored readings, release the read
button (#1) within 2 seconds. If you press and hold the read button #1, the meter will
repeat its read cycle, but will not add a new reading to the storage until the button is
released.
To view the readings press and release the calibration check button (#2). First the
meter displays the number of accumulated readings for one second, then the average of
those readings for two seconds. Then it displays the highest stored reading for two
seconds. The total "cycle" time is five seconds.
To erase all the accumulated readings, hold the calibration check button (#2) for
more than five seconds until the meter displays “0.”
To keep the accumulated readings in memory, release the calibration check button
(#2) before the total cycle time is complete.
The meter will accumulate up to 100 readings. After all 100 readings are stored, it will not
add new readings until the memory has been cleared. It will also continue to display the
average of all 100 readings as a reminder that the memory is full.
Readings below 6% will be displayed as “0”. Those above 40% will be displayed as
“99.9.” Neither will be added to the accumulated readings or used in calculation of
average or highest reading.
