Delmhorst Instrument BD-2100 - Manual (Page 4)

A hard Reset is required if, after changing the battery, the
display is frozen. This is sometimes caused by the interruption
of contact between the battery and battery lead wire. Resolve
this as follows:
Disconnect the battery. Press and hold the Read key for 15
seconds. Release the Read key. Press and hold the Check key
for 15 seconds. Release the Check key. Connect a fresh
battery to the lead wire in a single action, making sure to
align the poles properly and without interrupting contact. If
the display remains frozen, repeat the procedure. If this
procedure does not solve the problem, refer to the Service for
Your Meter section.
SET THE SCALE

Plaster/Concrete Reference) scale, or #3 Gypsum (Drywall).
h To change the scale, press the scale key # . The meter will
display the current scale for one second.
h To scroll forward through the scales hold the scale key #
while the current scale is displayed and scroll to the scale
desired.
h To scroll backward through the scales, press and hold the
set-point key
$ within one second of pressing and
releasing the scale key # . Continue to hold the set-point key
$ and the scale number will decrease.

Changing the scale will automatically reset the set-point
value to the default setting for that particular scale. Default
settings are as follows:
#1 Wood Scale - 15%
#2 0-100 Reference Scale - 85
#3 Gypsum Scale - 1%
CHANGE THE SET-POINT

INFORMATION ABOUT YOUR
READINGS
The meter will accumulate up to 100 readings in memory. After
all 100 readings are “stored” it will continue to display the
number of readings, the average, and the highest as a reminder
that the memory is full. It will not add new readings until the
memory has been cleared.
h To add a reading to the sum of all the previously stored
readings, release the read key
! within 2 seconds. To
avoid storing a reading, keep the Read key depressed until
the pins are no longer in contact with the material.
When taking and storing readings of a specific material, be
sure to “clear” the meter before switching to the next scale if
you do not want to group all of the readings together.
Readings below 6% will be displayed as -5.8 and readings above
40% will be displayed as a flashing 40.0. Neither of these types
of readings will be added to your accumulated readings.
TO CHECK ACCUMULATED
READINGS
This feature allows you to view the total number of all
accumulated readings for the selected material, the average of
those readings, and the highest stored reading.
h To view the readings press and release the calibration
check key
@ . First the meter displays the number of accu-
mulated 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.
h To erase readings hold the calibration check key @ for 5
seconds. All accumulated readings will be erased and the
meter will display “0”.
h To keep the accumulated readings in memory, release the
calibration check key
@ before the meter finishes the
above cycle.
