Quick Reference
CA1/ Trimming of measuring range
The measuring range, and consequently the measured value itself, can be corrected to
CE1
compensate for sensor tolerances to calibrate the instrument for use with other indica-
tors.
CA1 - for trimming at the lower end of the measuring range
CE1 - for trimming at the upper end of the measuring range
PC1 The PC1 resets the trimming performed using CA1/CE1.
