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 damage
the stored information.
Locking the Keypad
The keypad may be locked 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.
Note: Locking the keypad may cause the PLUS and MINUS keys to
function differently. (See “Pattern Adjustment”.) The zero key
will not function when the display is locked.
Pattern Adjustment (Battery Powered Display Only)
Whenever the readhead is disconnected from its power source, or the
display is turned off, and the readhead is moved over a pattern joint, the
displayed reading may be one or more patterns (+ 430mm) in error when
power is restored. This may also occur if the readhead is moved too
quickly in Model 150/250 systems.
To correct the error, place the digital display in ABS LOCK mode and
use the PLUS or MINUS keys to increment or decrement the reading
until the proper reading is displayed. Using this procedure will result in
NO LOSS OF ACCURACY to the system.
