RD1100 Operation Manual
11.3 System Overheating
The RD1100 GPR system is designed to operate to a maximum
internal
temperature of 70ºC or
158ºF. In situations of high ambient temperatures or long exposure to direct sun, this maximum
internal temperature may be exceeded and cause the system to fail.
If you suspect that the GPR sensor is overheating, shut it off and give it a chance to cool down
in a shady location before trying to run it again.
If the situation is such that the high temperatures or direct sun cannot be avoided, putting some
sort of shade over the GPR sensor may help to reduce the internal temperature.
11.4 Display Unit Problem
The Display Unit, which is weatherproof and rugged, should be handled in much the same way
as a notebook computer is. If the Display Unit does not power up, check the battery power and
all cable connections. If that doesn't work, contact the vendor.
11.5 Wobbly Wheels
Over time, a wheel may become wobbly, in which case you will need to tighten it manually.
For the rear right wheel only (which is connected to the direct drive odometer), insert a large
slotted screwdriver into the end of the axle (there’s already a slot there for it) and use a large
wrench to slightly tighten the wheel nut. The nut only has to be turned slightly, 1/8th -1/16th of a
turn is usually enough. Spin the wheel to make sure it is still free and not too tight.
11.6 Creating a Test Line for Data Quality
After receiving the system and getting comfortable with its operation, one of the best ways of
detecting any problems is to collect a line of data at a convenient, easily accessible location.
The line does not have to be too long but long enough to fill one screen is a good guide. This
data line should be saved electronically and perhaps plotted out on paper and dated. If there is
a suspected problem with the system later, this test line could be re-scanned and compared
with the earlier results.
NOTE: When comparing data, take weather and environmental conditions into account, as
changes can skew the comparisons slightly.
11.7 Contacting the Vendor for Service
When returning the system to the Vendor, have the following information available:
1.
GPR sensor Serial Number displayed in the System Information screen (under
System Test)
2. A brief description of when the error is happening and the operating conditions
(temperature, humidity, sunshine, system settings, etc.).
