6 Part Name DIGITAL INDICATOR Measurement Display Minus Display LED Status Display LED Operation Panel ZERO NIPPON TOKUSHU SOKKI CO.,LTD Operating button ZERO / Set current measurement values to zero.(auto-zero) OFF : Power ON while pressing the ZERO key limit setting display, change values. Change digit in function mode. / limit setting display, change values. Change digit in function mode / About Auto-Zero Set signal ON manually. Set signal OFF when pressed again. Register the settings in function mode. Auto zero function sets the measurement readings to Zero, during measurement operation. This function is not related with measurement modes or display values. This function sets the current measurement readings to Zero in Tracking Mode. Thus, even if you set the auto zero in Hold Mode, it will not work (cannot be zero). 〇 Perform auto-zero with external control input signal Make a short-circuit 6ZERO with 8COM1 in rear terminal block. The time should be over 200 msec. 〇 Perform auto-zero with manual key input ZERO Press key over 2 seconds. 6
