2) Move the cursor to the Tools field, and perform the clear table function.
3) Move the cursor to the BIN 1 LOW field.
4) Enter the limit value of the BIN 1 at BIN 1 LOW field using the numeric entry keys.
When one of the numeric entry keys is pressed, the unit softkeys (p, n, μ, m, k,
and M) are available, and so you can use these softkeys to enter the unit and
terminate the entry without hitting ENTER. When the limit value of BIN 1 is
entered in the BIN 1 LOW field, the BIN 1 low limit becomes – (absolute input
value), and the BIN 1 high limit becomes + (absolute input value).
5) The cursor will be automatically moved to the BIN 2 LOW field. Repeat step 4
until the limits of the BIN 3 is entered. After that, the cursor will be moved to the
2nd LOW field.
6) Enter the low limit value of the secondary parameter. After that, the cursor will be
automatically moved to the 2nd HIGH field.
7) Enter the high limit value of the secondary parameter.
8) If you want to change one of the high or low limit value. Move the cursor to the
HIGH or LOW limit field, and input the new value using the numeric entry keys.
9) If you want to change both high and low limit values. Move the cursor to the
HIGH or LOW limit field, press DEL— softkey to clear both high and low limit
values. Then repeat step 4 to input the limits again.
