ADJUSTING SCALING TO COMPENSATE VOLTAGE LOSS OR GAIN
STEP 1: Open up your GL900 APS software and connect your GL to it by matching up the USB ID on the unit and the software.
STEP 2: Once connected, you will be directed towards the page you see above. From here click on the settings button highlighted in red.
STEP 3: Once the settings window pops open, on the first tab which is the AMP Settings, turn on the scaling on the channels you would like to change (highlighted in red). Once turned on, the channels that have the scaling on will turn blue as shown above.
STEP 4: When a channel is turned on, a scaling window will pop open and from this window, you will set the scaling to your needs. If your GL is measuring off and you need to add .67 V to a channel then under the measured value on the left (highlighted in red) you would set the value of what you are measuring, such as from 0V to 2V. On the EU value (highlighted in blue), this is where you will set the offset or what you are scaling too. Because you want to add .67V, you will put the upper .67above 2 and same goes for the lower value as shown in the above picture. Select ok to save an exit out.
STEP 5: Once you have finished with your settings, you can click APPLY and then OK at the bottom left hand corner of the Settings window. You are now ready to start your adjusted measurements.
