Class 2 Low power in the visible spectrum (wavelength: 400 to 710 nm); eye protection normally afforded by aversion responses. Class 3A Direct intrabeam viewing with optical aids may be hazardous. Power of less than 5 mW max. for visible spectrum. Less than five times the output of the Class 1 for wavelengths other than the visible spectrum. Class 3B Direct intrabeam viewing may be hazardous. It is not hazardous to view the pulse laser radiation that does not focus due to scattered reflection and the power that allows safe viewing under certain conditions is less than 0.5 W. Class 4 High power; diffused reflection may be hazardous and may lead to skin hazards or fire. FDA/ANSI Class FDA definition ANSI description Class I/1 Limits applicable to devices that have emissions in the ultraviolet, visible, and infrared spectra, and limits below which biological hazards have not been established. A Class 1 laser is considered to be incapable of producing damaging radiation levels during operation and maintenance and is, therefore, exempt from any control measures or other forms of surveillance. Class IIa/2a Limits applicable to products whose visible emission does not exceed Class I limits for emission durations of 1,000 seconds or less and are not intended for viewing. Class II/2 Limits applicable to products that have emissions in the visible spectrum (400 to 710 nm) for emission durations in excess of 0.25 second, providing that emissions for other durations and/or wavelengths do not exceed the Class I limits. Class II products are considered hazardous for direct long-term ocular exposure. Class 2 lasers are divided into two subclasses, 2 and 2a. A Class 2 laser emits in the visible portion of the spectrum ((0.4 to 0.7 μm) μ ) and eye y t ti iis normally ll afforded ff d d protection by the aversion response including the blink reflex. Class IIIa/3a Limits to products that have emissions in the visible spectrum and that have beams where the total collectable radiant power does not exceed 5 milliwatts. Class IIIb/3b Limits applicable to devices that emit in the ultraviolet, visible, and infrared spectra. 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. Class IV/4 Exceeding the limits of Class IIIb and are a hazard for scattered reflection as well as for direct exposure. Class 3 lasers are divided into two subclasses, 3a and 3b. A Class 3 laser may be hazardous under direct and specular reflection viewing g conditions,, b t th but the diff diffuse reflection fl ti is i usually not a hazard. A Class 4 laser is a hazard to the eye or skin from the direct beam and sometimes from a diffuse reflection and also can be fire hazard. Class 4 lasers may also produce laser-generated air contaminants and hazardous plasma radiation. Label Indications EN Note: Use of controls, adjustments, or procedures other than those specified herein may result in hazardous radiation exposure.

The first and second right decimals will flash. 29 2.3 Back Up Setting When measurement conditions (i.e. measurement mode, comparative value, forced zero, etc.) are set, those setting data are stored in the internal non-volatile memory (EEPROM) as back up data. The number that the EEPROM can be overwritten is restricted. For the measurement conditions to be changed frequently, set the conditions with back up function OFF. (The EEPROM can be overwritten approximately 1 million times.) Operation 1 Select back up setting in maintenance mode. 12.34 ESC + t.set SEL t.sel (Normal measurement mode) (Light volume data writing) (Binary level set.) 2 SEL bavp (Back up set.)

Therefore, the back up function is turned OFF. The setting of back up ON/OFF is stored in EEPROM so that back up OFF is effective upon turning on power if back up OFF is set. Some settings are always backed up regardless of back up function ON/OFF. (Back up ON/OFF can be set.)

Set the back up function to ON in back up setting in maintenance mode. (The default setting is back up function ON.) 2. Set the measurement mode to bar diameter measurement mode and also set the necessary measurement conditions (i.e. communication, bank, etc.). In this setting, set the items which are not to be changed often. 3. Set the back up function to OFF in back up setting in maintenance mode. 4. Start measurement. The measurement conditions can be changed using a front panel or communication, but not stored in EEPROM. 5. Turn ON power. The measurement starts with the conditions being set in the operation 2. ■ Displays when back up setting and measurement conditions are changed. When changing measurement conditions on a front panel, the display differs depending on back up function ON or OFF. When measurement conditions are changed and L is pressed, the LED indicator will be lit once and the next display will appear when back up function is ON. When back up function is OFF, the next display will appear without the LED lit. 31 2.4 Protection Setting Protects the setting values or internal data against unexpected front panel operations. However, communication commands by RS-232C can not be protected. There are two parameters for protection setting. Once the setting is turned ON, the menu will disappear.

Refer to “Section 3. Setting Mode” in page 39. ■ Outputting measurement data The Z4LC outputs the following data according to the result of measurement. [Measurement Value Output] - Binary data output: Outputs measurement results in 12-bit binary form. Refer to “4.2.1 Binary Data Output” in page 75. - Linear output: Outputs measurement results in current 4 to 20 mA. Refer to “4.2.2 Linear Output” in page 75. [Discrimination Result Output] - Discrimination data output: Outputs the result HI, PASS or LOW. Refer to “4.2.3 Discrimination Data Output” in page 76. The following data are sent by RS-232C communication: - Measurement data output: Sends measurement values. Refer to “4.5.1 How to Use [O] Command” in page 84.   - Edge position data output: Sends edge position data.              Refer to “4.5.2 How to Use [e] Command” in page 87.   74 4.2 Measurement Value and Discrimination Result Outputs 1 Binary Data Output Outputs the measurement result in 12-bit binary form (D0 to D11).  【 e.g.】 】 When the measurement result is 12.34:      (1234)10=(4D2)16=(010011010010)2 → D1,D4,D6,D7 and D10 turn ON.    Please note that D0 to D11 turn OFF while in pin diameter determination or pin pitch determination mode.    Notes Binary data output does not change even if forced zero function is set.

ZERO LED will be lit. When ZERO / L on a front panel is pressed or ZERO is input externally for 0.2 to 0.8 sec. while measuring a sample of the reference object, forced zero function turns ON and the measurement value is set as a forced zero value. Then, ZERO LED will be lit. Notes If ZERO / L on a front panel is pressed or ZERO is input externally for 0.2 to 0.8 sec. while forced zero function is ON, the measurement value is set as a forced zero value so that the forced zero setting can be performed continuously. When ZERO / L on a front panel is pressed or ZERO is input externally for 1 sec., forced zero function turns OFF and ZERO LED will be turned off. Notes If forced zero is input while enable input is effective, the last confirmed value is set as a forced zero value. 78 2 Forced Zero Setting by Communication Forced zero can be set by RS-232C communication. 】 Header: STX, Footer: ETX   【 e.g.1】 Turning ON forced zero function (STX)(Z)(1)(ETX) 】 Header: none, Footer: CR   【 e.g.2】       Turning OFF forced zero function (Z)(2)(CR) When codes are received and the setting has been changed correctly, the new setting becomes effective immediately after “OK” is sent.
