Z-Max Surveying System Operation and Applications Manual
Base System Troubleshooting
The base system of the Z-Max has two basic functions, track satellites in order to
collect raw satellite data at its position, and transmit this data to any rover system
within range of its radio. The inability to perform either one of these functions renders
the base system useless. Therefore, the path to troubleshooting the base system
should begin with these two items.
GPS Receiver Does Not Track Satellites
One function of the display on the front panel of the Z-Max receiver is to inform the
user of the number of healthy satellites being tracked and used by the receiver. This
information is also available through the field application software running on the
handheld computer. Refer to the field application software documentation for details
on how to access this information. Using this feature, you find that the receiver is not
tracking satellites. Follow the outline below to determine the cause of this problem.
Step 1. Is the GPS receiver powered up?
To determine if the receiver is powered up, examine the power LED on the front panel
of the receiver. If the LED is on (red or green), the receiver is on.
Receiver not powered up
1.Turn on the receiver.
Press and hold the power switch on the left side of the Z-Max front panel. The
button must be held for a few seconds since there is a delay in power on. You will
see the power LED turn on and the display will begin to show text.
Go to step 2 if the receiver does not power up.
2. Check the power source.
The Z-Max supports both internal (Power Module) and external power sources.
a. If using the Power Module, press the power level indicator button. If low,
replace the module with a good one and turn on the receiver.
b. If using external power, check to ensure the power cable is properly
connected to both the battery and the receiver.
(i). If the cable is properly connected, check the power level of the
external power source. If low, replace the battery with a charged
battery and turn on the receiver.
