1.
Turn the gauge on. It will perform stabilization procedures.
Please allow it to warm up for ten minutes.
2.
Place the reference block on a solid surface with a density of
1600 kg/m
3
(100 pcf) or greater, such as compacted soil,
asphalt, or concrete. The gauge should be at least 3 meters
(10 ft.) from any large object such as a vehicle or wall. There
should be no other radiological sources within ten meters
(30 ft.).
3.
Place the gauge on the reference block with the keypad end
against the metal plate between the raised edges. Be sure
the gauge is properly seated on the recessed surface of the
reference block.
4.
Remove the padlock from the source rod. Leave the source
rod in the SAFE position.
5.
Turn the PWR/TIME switch to the SLOW (4 minute)
position. Press the
〈
SHIFT
〉
and
〈
STANDARD
〉
keys at the
same time. In the display window you will see the gauge
counting and ERR in the upper-left corner.
6.
After four minutes the counting will stop. Both moisture and
density standard counts are stored in the gauge. Press the
〈
DS
〉
key and record the density standard count. Press
〈
MS
〉
and record the moisture standard count.
7.
Return the reference block to the case.
8.
Record the standard counts in the log book.
NOTE
To verify gauge stability, use the daily log of
moisture and density standard counts.
