KEY LOCK
To activate the Key Lock function press and hold the ON/OFF key and then
momentarily press the UNITS key. The word LOCK
LOCKLOCK
LOCK will appear in the upper left
corner of the readout. When LOCK
LOCKLOCK
LOCK is displayed, the +, DATUM and – keys
become inactive to prevent accidental changes of the (calibrated) current
displayed position. To de-activate the Lock function, press and hold the
ON/OFF key and then momentarily press the UNITS key.
NOTE: The Lock function can also be enabled/disabled through
programming. This allows a more permanent Lock function since
programming can be disabled with a hardware jumper inside the readout thus
preventing any front panel programming changes.
See Section 3: Programming, Programming Parameter Pr3.
RESOLUTION
The readout can be configured to display measurements in any of three
different resolutions.
1. Low– the resolution is: .1in or .1mm.
2. Normal– the resolution is: .01in or .01mm.
3. High– the resolution is: .001in or .01mm
The display of fractions remains the same for all settings: 1/16, 1/32 & 1/64
See Section 3: Programming, Programming Parameter Pr4.
RESTORE READOUT TO FACTORY SETTINGS
Press and hold the ON/OFF and UNITS keys for 10 seconds with readout power
turned off. This will perform a full segment LCD test, display the current
firmware version, and reset all programming parameters to factory defaults.
