Incrementing/Decrementing the Display
The PLUS or MINUS keys on the digital display are used to adjust a
reading. For instance, if the display needs to read greater than its
current value, use the PLUS key. Conversely, to reduce the current
displayed reading, use the MINUS key. This function is used to preset a
value in the system. When the display is in the locked mode these keys
will either:
1. No longer function, preventing accidental adjustment of readings, or
2. They will be used for another function: pattern offset (only in the
Basic displays).
Note: When pressing the PLUS or MINUS keys, the display scrolls
slowly for a couple seconds and then speeds up.
Reverse Scaling
When setting a zero point on ProScale, moving the scale (or readhead)
in one direction will produce positive readings. Moving the scale past
zero in the opposite direction will produce negative readings. Reverse
scaling means changing the orientation so the positive readings become
negative and negative readings become positive. To reverse the
readings, the position of JP3 (inside the display) must be changed. See
the chart of Display Options for more information.
Auto Save
When power is turned off, ProScale remembers the current
measurement and current mode of operation. When ProScale is turned
back on, the user can continue where they left off. It's not necessary to
zero the reading or change the mode. Also, keystrokes are not
recognized when power is off, so accidental keystrokes will not change
the stored information.
Locking the Keypad
The display allows the user to lock the keypad so the current settings
can't be accidentally changed by depressing the ZERO, PLUS or MINUS
keys. To lock the keypad proceed as follows:
1. While depressing and holding the ON/OFF key, momentarily press
the MODE key.
2. Release the MODE key and then the ON/OFF key. The display
should now indicate “LOCK” in the upper left corner.
3. Use the same procedure to UNLOCK the keypad.
