Humboldt H-4114SD.3F Electrical Density Gauge - Manual (Page 8)

6. Battery Charger Cable
In use, the EDG runs on battery power supplied by a Lithium Ion Battery.
The battery provides about 60 hours of runtime from a fully charged battery.
The battery needs to be charged periodically. To charge it, use the
supplied cable located in the accessory caddy. To use, plug the Battery
Charger Cable into an electrical outlet and plug the other end into the port
at the top right of the EDG's control panel. To fully charge the battery from
a critically low point to full takes about 6 to 8 hrs.
Best practice is to keep the battery charged. The EDG can be stored
between usage plugged into a power source via the Battery Charger Cable.
For extended periods of downtime, it is recommended that the Battery be
turned off for storage.
To do this, remove the six thumb screws holding the faceplate of the EDG in
place. Carefully lift off the faceplate. Be careful that you don't pull any wires
out of their connections. The battery is located at the bottom of the inner
EDG compartment. At the top of the battery mount is a small sliding switch.
Move the switch to the right to turn the battery off.
7. Darts
The EDG is supplied with a set of four (4) 6" Tapered Darts. These are
stored on the lower level of the Accessory Storage Area. Darts are available
in five different lengths: 4", 6", 8", 10" and 12". Dart lengths should be
used to correspond to lift height being used in the project.
8. Hammer
The EDG is supplied with a hammer for driving Darts into the material to
be tested. It is stored in the lower level of the Accessory Storage Area.
9. T-Handle Probe
The T-handle probe is used to assist in placing the Temperature Probe into
the material to be tested. It is stored in the lower level of the Accessory
Storage Area.
10. Calibration Device
The Calibration Device should have the same serial number as your Gauge
and the Soil Sensor. It is used for a quick, one-point calibration check to
make sure the Gauge and Soil Sensor are working properly. It is suggested
that this test be run before each day of testing.
