Using the Lineariser
You can enter up to 10 calibration points, to generate a curved function between input
signal and displayed value. Each point MUST be greater in value than the previous
one and the meter must be set for DIRECT calibration method.
(Note - linearising is not available on MEM-08 option meters or meters set for
THEORETICAL calibration)
1) Calibrate the first two points using the ZERO pushbutton for the lowest
input load (0) and SPAN pushbutton for the 2nd input load, using the direct
calibration routine. Do not calibrate SPAN with 100% input !
2) Apply the 3rd input load and then press both ‘LINEARISER’ Buttons.
Display should confirm by saying POINT3.
Adjust the reading to the desired value using the DIGIT SELECT and the
UP/DOWN pushbuttons.
Press OK when done.
3) Apply the 4th input load and then press both ‘LINEARISER’ Buttons.
Display should confirm by saying POINT4.
Adjust the reading to the desired value using the DIGIT SELECT and the
UP/DOWN pushbuttons.
Press OK when done.
You can repeat this process for as many other calibration points you wish to apply,
up to a maximum of 10.
There is no time limit with these settings, so you can take as much time as you need to
adjust each point. But, power must not be removed from the meter during the procedure,
or your settings will be corrupted.
IMPORTANT!
Set lockout switch 3 to its ‘ON’ position after setup, to save your settings.
Do NOT move switch 1 or 2. If your readings change when you move switch 3, make a brief
connection between terminal 7 and 10 to clear any tare offsets.
