2.3 Auto-Zero Function
The displayed value can be instantaneously reset to "0000" by pressing the
[ZERO] key or input through the AUTO-ZERO input terminal. The increase or
decrease in the value measured after activating the auto-zero function can be
displayed using "±" (plus or minus). This function simplifies zero-point adjustment
at product type changeovers.
Using the front panel key
• Press the [ZERO] key to reset the displayed value to "0000".
• The value displayed just as the key is released is reset to "0000".
Using the AUTO-ZERO input terminal
Short-circuit the ZERO 4 and GND 7 terminals to activate the auto-zero function.
Canceling the auto-zero function (Restoring the value reset using the auto-zero function)
Press the [ZERO] key for 3 seconds to cancel the auto-zero function.
Note 1: When an offset value is set, the offset value is displayed when the auto-
zero function is activated. For details, see "Offset function [x]" (
➮ pages 40 and 41).
Note 2: When using the internal trigger function ( ➮ page 46), adjust the trigger
level after activating the auto-zero function. (The internal trigger function works with
regard to the value displayed after the auto-zero function is activated.)
If frequently activating the auto-zero function using the external input
terminal, set the panel-lock function to ON to protect the memory. Then, the
displayed value will not be stored in the internal memory.
For details of the panel-lock function, see "Panel-lock function [
J]"
( ➮ page 43).
