[. . . ] Confirm the selection. SUB FUNCTION SETTINGS 2 Set the ECO mode. Select [ECO]. Confirm the selection. SUB ZX-GT User's Manual Changing Display Conditions 79 Setting Communication Conditions RS-232C Communications Specifications Set the communication specifications for the Controller matched to the communications specifications of external devices. After setting the communications specifications, the Controller must be turned OFF then back ON again to enable the settings. Setting value BPS (baud rate) LEN (data length) S. BIT (stop bit) PRTY (parity) Range 1200, 2400, 4800, 9600, 19200, 38400 (default value: 38400) 7, 8 (default value: 8) 1, 2 (default value: 1) NONE (none), ODD (odd), EVEN (even) (default value: NONE) HD. FT ST. ET (STX+ETX), CR, CR. LF (CR+LF) (header/footer selection) (default value: CR) 1 Select the special setting. Select [SPCL]. Confirm the selection. SUB 2 Set the baud rate. Select [BPS]. Confirm the selection. SUB 3 80 Set other items by the same procedure. Setting Communication Conditions ZX-GT User's Manual Setting the Binary Output Cycle Set the cycle at which binary output is performed. After setting the binary output cycle, the Controller must be turned OFF then back ON again to enable the settings. Setting value 1 to 500 (ms) Description Set the output cycle. (default value: 1) The measurement result is output at the output cycle you set here. 1 Select the special setting. Select [SPCL]. Confirm the selection. SUB 3 FUNCTION SETTINGS 2 Set the output cycle. Select [CYCLE]. Confirm the selection. SUB ZX-GT User's Manual Setting Communication Conditions 81 Special Functions Zero Reset Memory Select whether or not to hold the measured value after the zero reset was performed (zero reset level) when the power is turned OFF. Setting value OFF ON Range Zero reset is canceled when the power is turned OFF. (default value) The zero reset level is saved when the power is turned OFF. Important If zero reset memory is set to [ON], the zero reset level will be written in the Controller's nonvolatile memory (EEPROM) each time a zero reset is performed. The EEPROM can be written a maximum of 100, 000 times. Setting the zero reset memory to [ON] can, therefore, use up the life of the memory and lead to malfunctions. Executing and Canceling a Zero Reset p. 47 1 Select the special setting. Select [SPCL]. Confirm the selection. SUB 2 Set zero reset memory. Select [ZRMEM]. Confirm the selection. SUB 82 Special Functions ZX-GT User's Manual Display during a Zero Reset Set the zero reset memory function to set the reference value to a value other than 0 (zero). Setting value 00. 000 to 59. 999 (mm) Range Set the reference value. (default value: 00. 000) 1 Select the special setting. Select [SPCL]. Confirm the selection. SUB 3 FUNCTION SETTINGS 2 Set the reference value. Select [ZRDSP]. Confirm the selection. SUB ZX-GT User's Manual Special Functions 83 Key Lock The key lock function disables all Controller keys. Once the keys have been disabled, no key input will be accepted until the lock is canceled. This function is useful for preventing inadvertent changes to settings. The mode and threshold switches are still enabled even when the key lock function is ON. Setting the Key Lock 1 Apply the key lock. Hold down these keys until [OK] is displayed, and then release the keys. SUB Canceling the Key Lock 1 Cancel the key lock. Hold down these keys until [OK] is displayed, and then release the keys. SUB 84 Special Functions ZX-GT User's Manual Switching Banks The ZX-GT can hold up to two sets of settings, which are called a "bank". Banks can be switched from an external device when changing the device setup. Important The following data can be saved in memory as settings of banks. · HIGH and LOW thresholds · Hysteresis width · Number of IC leads, IC lead pitch, IC lead pitch tolerance (IC lead pitch judgment mode) · Number of IC leads, IC lead width, IC lead width tolerance (IC lead width judgment mode) · The first and second specified edges (Specified edge measurement mode) Setting the Bank Switching Source Set from where switching of banks is to be instructed. 3 Setting value KEY I-O Description Bank switching is performed by operating the control keys. [. . . ] 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. 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. Limits applicable to devices that emit in the ultraviolet, visible, and infrared spectra. [. . . ]
