After completion of the data edit, key must be pressed. Otherwise, pressing the
key, new data will not be written into the internal memory, the previous value for
the parameter is kept.

4.4.3 Setting CR Values
When operate in CR mode, the VFD displays CR mode.

There are three resistance ranges for CR operation: high resistance range, middle resistance
range, and low resistance range. The current setting of all resistance ranges can select high,
middle or low 3 types of ranges. ALL resistance levels are programmed in ohms (
Ω). The
following examples show how to set the CR values of Load module for model 63630-80-60.
1.
Select the resistance range
Select proper range, by pressing key, until the LED of the desired range above
the key is lights up. High range is used when higher resistance level is required,
and LOW range is used when better resolution is required.
Select LOW range, by pressing key, until the LED “L” above the key
lights up.
The sequence of range selection after pressing key is as follows:
High range

Middle range

Low range goes back to High range.
2.
