RetroSign GR1 & GR3 · Retroreflectometer
GPS State:
(
Control the GPS function
) (Optional)
The GPS receiver can be disabled if desired, the main reason for doing this would be to reduce the overall power con-
sumption maximizing the number of possible measurements on the available battery charge.
Tag Reader:
(
Control the RFID or Barcode reader option
) (Optional)
The GR1 and GR3 have an option for inputting data from an external RFID or Barcode reader. This will make it possi-
ble to use RFID tags or standard Barcodes to uniquely identify signs.
Enabling the reader option changes the way the instrument behave when taking measurements. When no reader is
connected this option must be disabled
When enabled, the instrument will ask for a Tag on the first trigger. When the tag has been read the instrument will do
the measurement on the second trigger. See appendix E
When the Mean Calculation is enabled the instrument will only ask for the tag on the first measurement in a series
(Mean Count < 2). This allows for doing multipoint measurements with the same Tag code.
After clearing the mean calculation the instrument will again ask for the Tag on the first trigger.
Remove Latest Measurement:
(
undo the most recent measurement
)
It is possible to remove the most recent measurement record from the work log. To maintain data integrity only one da-
ta record can be removed and only if it is done before the instrument is turned off.
