Page 129: Using The Zero Reset Function
AUXILIARY FUNCTIONS Using the Zero Reset Function When the zero reset function is used, the reference value “0” is registered as the height and the measured value can be displayed and output as a positive or negative deviation (tolerance) from the reference value.
Page 130 Section 6 AUXILIARY FUNCTIONS Setting Offset Values Set an offset value when the reference value for zero reset is a value other than 0. Moving to FUN and SPCL Set the mode switch to FUN. Use the LEFT and RIGHT Keys to display SPCL on the main display.
Page 131 The minimum display value is − 19,999 and the maximum is 59,999. If the measurement result after zero reset is less than the minimum, the display will be − 19,999. If the measurement result is greater than the maximum, the display will be 59,999. Zero reset can be executed only when the measured value is ±...
Page 132 Zero reset is released when the power is turned OFF. Turn OFF zero reset memory if, as in the example below, the zero point is reset for each measure- ment. If zero reset memory is enabled, the zero reset level data will be written in the Amplifier Unit non-volatile memory (EEPROM) at each zero reset.
Page 133 Selecting Whether or Not to Enable Zero Reset Memory Press the UP or DOWN Key. The sub-display will flash. Use the UP and DOWN Keys to select ON or OFF. ON: Zero reset memory enabled (default) OFF: Zero reset memory disabled Press the ENT Key to confirm the selection.
Page 134: Key Lock Function
AUXILIARY FUNCTIONS Key Lock Function The key lock function disables all Amplifier Unit keys. Once the keys have been disabled, no key input will be accepted until the lock is released. This function is useful to prevent inadvertent changes to settings.
Page 135: Initializing Settings Data
AUXILIARY FUNCTIONS Initializing Settings Data This function resets all settings to their default values. Linearity adjustments, however, are not initialized using this function. To initialize linearity adjustment data, perform initialization in linearity adjustment mode. Initializing Adjustment Settings, p. 59 Function Default Value No.
Page 136 Section 6 AUXILIARY FUNCTIONS Set the mode switch to FUN. Use the LEFT and RIGHT Keys to display INIT on the main display. Press and hold down the ENT Key. The sub-display will display “-----”. Release the ENT Key once OK is displayed on the sub-display.

Page 143 The response speed of the judgement outputs is calculated as the measurement period x (No. of samples to average setting + 1). 2. The output can be switched between current output and voltage output using a switch on the bottom of the Amplifier Unit.

Page 146 APPENDICES 1. Resolution: The resolution is the deviation ( ± 3 σ ) in the linear output when connected to the Amplifier Unit. Notes: The above values indicate the deviations observed 30 minutes after the power is turned ON. (The resolu- tion is measured with the standard sensing object at 1/2 of the measurement distance range, with the Amplifier Unit set for the maximum average count of 4,096 per period.)
