Executing Reference Zero Reset p. 115 ADJ mode-MENU/VIEW key-[OUT]-[ZERO] Setting value ZERO Description Sets the offset amount. Range: -999. 99999 to +999. 99999 (default value: 0) Note To change numerical values, use the key/ key, and to change the number of digits use the key/ key. 114 Setting Zero Reset ZG2 User's Manual Executing Reference Zero Reset 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. In the RUN mode, the measured value can be reset to "0" at any time during measurement. 1 2 Switch to the RUN mode. Set the object to be used as the reference in place. 3 (reference value) FUNCTION SETTINGS Zero Reset indicator 3 Press the SET key. The Zero Reset indicator lights, and the current measured value is registered as 0 (zero). Note · To cancel a zero reset, press and hold the ESC key for 2 seconds or longer. · Zero reset can also be executed and canceled by an external input. · A value other than zero also can be set as the zero reset reference value. Setting the Offset Value p. 114 ZG2 User's Manual Setting Zero Reset 115 Bank Settings The ZG2 can hold up to 16 sets of settings, which are called a "bank". Bank 1 is displayed as the default bank when the Smart Sensor is turned ON. Tasks and Bank Data p. 53 Bank Switching (change of device setup) The currently selected bank can be switched to other banks. Switching of banks is instructed by operating Controller keys, external signals or communication commands. FUN mode-[BANK]-[SWITCH] Setting value BANK1 to BANK16 Description Selects the target bank. (default value: BANK1) Note Switching banks by external signals p. 129 Switching banks by communication commands p. 160 Copying Bank Data The settings of other banks can be copied to the current bank. FUN mode-[BANK]-[COPY] Setting value BANK1 to BANK16 Description Selects the copy source bank. (default value: BANK1) Important After executing a bank copy, switch to the RUN mode once to save the settings. Settings are cleared when the Smart Sensor is turned OFF after you just copy the settings. 116 Bank Settings ZG2 User's Manual Clearing Bank Data The content of banks can be cleared.

This setting is automatically specified according to the type of the connected Sensor Head. [. . . ] Class IIIb products include laser systems ranging from 5 to 500 milliwatts in the visible spectrum. Class IIIb emission levels are ocular hazards for direct exposure throughout the range of the Class, and skin hazards at the higher levels of the Class. ANSI description Class 3 lasers are divided into two subclasses, 3a and 3b. A Class 3 laser may be hazardous under direct and specular reflection viewing conditions, but the diffuse reflection is usually not a hazard. Class IIIb/3b Class IV/4 Exceeding the limits of Class IIIb and are a A Class 4 laser is a hazard to the eye or skin hazard for scattered reflection as well as for from the direct beam and sometimes from a direct exposure. Class 4 lasers may also produce laser-generated air contaminants and hazardous plasma radiation. 230 Requirements from Regulations and Standards ZG2 User's Manual Compliance with EC Directives CE marking Applicable directive Low-Voltage directive Compliance (*1) *1 Safety category EMC directive Complied (*1) B Exception For details of detailed compliance levels, we have issued the "EC Declaration of Conformity: EN45014.
