Delmhorst Instrument Accuscan - Manual (Page 6)

METER/BATTERY CHECK
hHold the meter in the air and away from any object. Your
fingers must not make contact with the sensor plate while
performing this function.
hPress and hold the check button (3) until the green light
stops blinking.
h The battery voltage is sufficient if the needle pointer
moves to within the green band (20%) on the wood
scale. Any reading within this green band on the dial is
acceptable. Make sure the sensor pad is not making
contact with anything when checking the meter.
h If the needle does not read “20” it is likely an indication
of a low battery. If this occurs, change the battery
(9-Volt) 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
a proper reading, return it to DELMHORST for service.
See
“Service for Your Meter” section for details.
***A low battery indication is also provided during the read
cycle. If, while taking a reading, the LED blinks, the
battery voltage is below 6%.
TAKING A READING
hSelect the appropriate scale by pressing and releasing either
the Reference Scale or the Wood Scale button. Hold the
meter in the air and away from any object when making the
scale selection.
hThe meter will turn on, and the LED will flash several
times. This action also performs an auto calibration, which
ensures that meter readings will be stable, repeatable, and
virtually unaffected by environmental conditions.
hWhen the LED stops blinking, the unit is ready to take a
reading.
hPlace the meter on the surface to be tested.
hHold the outer sides of the unit and apply slight forward
pressure on the meter to minimize the amount of air
between the sensor plate and the material being tested.
hIf you want to read continuously, press and HOLD the Stay
On button (1) to keep the unit ON. If you release the Stay On
button, the meter will turn off after 2 minutes 30 seconds.
hTo turn the meter “ON” after 2 minutes 30 seconds, hold it
in the air and away from any object. Press the Stay On
button or appropriate scale button again.
