Setting the Range

The range shown on the LCD screen can be adjusted to suit the different sensors being used on the GTA-4100R
card. Follow this procedure to change the range:
1. Ensure that the switch bank 2, position 6 (DisAL) is turned off before proceeding.
2. Confirm that jumper JP5 or JP6 are in place.
3. Press the F.Scale button and this will show the set range for the channel.
4. Hold the button down for 3 seconds and the range will start stepping up between 0-1, 2, 3, 4, 5, 10,
15, 20, 25, 30, 40, 50, 75, 100, 150, 200, 300, 500, 1000, 2000.
NOTE: The default range is 100.
5. Decimal points are pre set as follows:
a. Two digits from 0-5
b. One digit 10 to 100
c. No decimal point 100-2000
NOTE: The range and decimal point settings stated here are standard but others can be configured on
request.
6. Once the range has been set, you can remove jumper JP5 (top channel) or JP6 (bottom channel) to
stop accidental changes after installation.
