As the instrument speed is lagging, when instruments detected speed is greater than 8Km/h Shi, instrument overspeed alarm will be issued. Short-distance transport, vehicle traction can be used, but must lock the rack, measuring wheels and suspension, traction speed is not greater than 25Km/h.

c. Test is complete, be sure to remember to power off the wireless data acquisition system, so that the battery runs out.

d. Do not use for a long time, you must remove the collection within the battery, battery leakage was substantially damaged capture circuit board. Failures due to battery leakage do not included in the reservation. Using high-energy alkaline cells could effectively prevent battery leakage. Recommended battery: nanfu shaped ring, Duracell MX1500, Duracell MN1500, Super GP 1, Energizer E91, double deer new century energies, Wan sheng MAXELL LR6 。 Please pay attention to the battery under voltage of the collector indicates battery indicator or the master controller, when the battery is low, replace the batteries immediay, low battery will cause measurement error.

e. Sensor, the collector, control boxes and other electronic parts absoluy to avoid rain, damp, and so on.

f. Rack bearing, steering mechanism and other moving parts to each 6 Months raise a lubricant to prevent wear and rust. Before use to check whether the bolts fastening.

g. Wear can affect the measurement accuracy of the measuring wheel, instruments using more than 2 Years later, depending on wear replace measuring wheel. Standard measuring wheel diameter for 160mm. Rubber hardness HA(55-70).

h . When shorten communication distance (2-5M), or compley unable to communicate, may be the radio antenna is damaged, please check the antenna connector, is dropped.

 

2 ) Common failure and troubleshooting

a. Printer will not print. Open the main controller Panel, check the printer data cable and the power cord is loose.

b. Traffic is not reliable. Communication distance is too far, the host controller and wireless data acquisition device is within sight distance range, communications antennas for damage, broken.

c. Test results that were significantly large deviation, check whether the measuring wheel spring loose, transport wheels, rack has become loose. Displacement sensors need to be aligned, or the battery is low.

d. Lines, no change on the primary controller, deviations. Displacement sensor plug is loose.
