Daily Operation of the Detector without a Gate and Counter
The following steps should be followed before each sampling
session. For more detailed information, please see Part 4.
1. Mount the Detector on legs, a table, or some other appropriate device that
provides a 10 to 30 degree downward slope and minimal wobble. Small
vibrations and wobbling may adversely affect performance.
2. Verify that the desiccant is not saturated. If the desiccant is mostly
orange or pink, replace the cartridge. Please see the Appendix for
information about desiccant options.
3. Provide the detector with power. Confirm the detector has C-cells if so
equipped. Otherwise, connect the power cable to the "Power Connector"
on the rear panel. If the battery pack is being used, the red battery clip
should be attached to the positive (+) battery terminal and the black
battery clip attached to the negative (-) battery terminal. If the 120-volt
power supply is used with an extension cord, it is recommend that the
connection to the extension cord be made inside the battery box,
with the lid strapped on. This will reduce the possibility of the connection
lying in water, and will better insure that it will not be accidentally
disconnected.
4. Remove all tools and paraphernalia from the top of the detector.
5. If available, turn on water and establish a flow of water through the
detector so that most of the tunnel’s bottom surface is wet.
6. Turn on the Detector with the "Power" switch. The LED bar graph will first
display a bar representing the energy left in the C-cells or the battery pack.
It will then retract to the left for several seconds while the microcomputer
initializes itself. Approximately 15 to 20 seconds after turning on the
power, the display will start showing the strength of detected magnetic
signals.
7. If the "Low Battery" or "Dead Battery" LED is on, replace the C-cells with
two fresh alkaline c-cells or recharge the external battery, if so equipped.
