Changing and storing upper and lower comparison values

You can change the upper and lower values that are used for comparing with

the measured load. Up to eight pairs of upper and lower values can be stored
in memory. The values in the table below are already stored as default

values. (On the CM-5-003 model, a decimal point will be displayed next to the

10

1

digit.)

Pair number display

This display shows you that

Pair 1

is specified.

To change which pair is selected, press the

key. The pair number will change in the following order:

"

1→2→3→4→5→6→7→8→1

". Select the pair that you want to change.

2. Press the

key.

--- The display will change to show the upper-limit.

Lower-limit display

"

" means that you can now

change the upper-limit value.

Pair number display

The digit next to a flashing decimal point
can be changed.

Now for practice, try to change the current upper-limit value for pair 1.

Change the current value "1000" to "2250."

Depending on the model, the position of the decimal point will vary. It will either be next to the 10

1

or

the 10

2

digit. See the section, "Digital load display," on page 27.

3. First, change the value of the 10

3

digit.

Each time you press the

key, the number shown in the 10

3

digit place

(

next to the flashing decimal

point

)

will change, in the following order: "

2→3→0→1→2

".

(

The maximum number available in

the 10

3

digit place is "3."

)

Change this digit to " "
