:
Indicator LED Displays Three Types of Information
1) Battery Status
– Battery charge state indicated by flashing LED at indicated level
100/50/25%.
2) Power Level Setting
– The flashing LED indicates the transmitter output power level setting
(Low/Medium/High).
3) Transmitter output Check
– The 810Dx transmitter has a feature that will check the output of
the transmitter taking into account the entire locate circuit including the resistance offered by
the utility, the ground, the connection point and the Power level selected. The indicated
Output Level is used to determine the potential quality of the locate. Most importantly the
Output Level check will indicate if the Output is too low for good locate. Low Output Level is
an indication of high resistance in the circuit reducing the Output Level. Low Output Level
means low signal strength and the receiver may not determine centerline or depth with any
accuracy. Always improve the ground and or utility connection to increase the Output Level.
To check the transmitter Output Level, press and hold the Power Level Output Button. An
LED will indicate the output level at the Power Level selected. Refer to the Output Level and
Locate Quality Chart Figure 4-4. Improve the ground and or direct connection if a Low or no
Output Level is indicated.
