Direct Calibration, no linearisation
Set your calibration method to DIRECT - see previous page.
Assume we want to calibrate a weighing platform, rated at 250kg. We have a 200kg calibration
weight. (Use at least 60% rated load for calibration. 100% ideally)
First, calibrate the full scale (SPAN) reading. We do SPAN first, because in the SPAN procedure we
can set the
decimal point position of our measurement, to set resolution.
SPAN Calibration . Apply your calibration load and press the Set2 button for 3 seconds.
Display will show ‘direct’ , ‘set HI’ . Press OK. You will see that one digit is brighter than the others.
You can edit the value of a brightened digit with the UP/DOWN buttons.
You can brighten other digits with the DIGIT button.
Go through each digit in turn, to set the desired value of your calibration load.
Press OK when done.
To set the decimal point position , press the Set2 button for 3 seconds whilst in the numeric
setting stage . You’ll see all decimal points light, with one brighter than the rest. Use UP or DOWN
buttons to move the brightest decimal point and press OK when in the desired position.
ZERO Calibration. Remove your load and press the Set1 button for 3 seconds.
Display will show ‘direct’ , ‘set LO’ . Press OK. You will see that one digit is brighter than the others.
You can edit the value of a brightened digit with the UP/DOWN buttons.
You can brighten other digits with the DIGIT button.
Go through each digit in turn, to set all digits to 0. Press OK when done.
