Two different keys are needed
Wear badge
Make entry in sign out diary
Place travel papers on truck dashboard in plain view within driver’s reach (transport gauge in locked box
only)
Warm up machine 10 minutes – Set on plate with probe opposite butt plate
Take standard count – record standard counts in diary. Follow instruction manual.
1% Density Deviation, 2% Moisture Deviation
Enter proctor value from materials
Enter applicable moisture correction – See pages 3-4 in Troxler Manual
Sign back in at end of day and clean equipment
TROUBLE SHOOTING
Do not charge batteries until “low battery” appears (2-3 hours remaining)
If the display reads “GM Tube A Error, Service Required”, remove and replace fuse; retry entry.
See 203.5 of the Engineering Policy Guide for information on testing with Nuclear Moisture-Density Gauges.
See http://scweb4/hq/co/radiation for routine maintenance issues.
Battery Voltage: 3.6, Normal
3.35-3.4, Battery low but serviceable
