ProScale M150, M250 and all products with General Purpose LCD Digital Displays 31 of 31 MONitor The Digital Display has the ability to monitor a position to detect position drift or measurement variance. To activate the monitoring mode, position the readhead to the desired location and momentarily press the MON key. The MON symbol will flash on the display to indicate that the position monitor mode is active. If the readhead moves outside the programmed tolerance the displayed reading flashes, indicating a drift condition. When the readhead is moved back within the programmed tolerance, the displayed reading will stop flashing. To exit the monitor mode, momentarily press the MON key. The MON symbol will stop flashing and the currently displayed position will also stop flashing. NOTE: Position monitor mode can only be activated while in the ABS measuring mode. If the ABS/INC key is depressed while monitoring, the position-monitoring mode is automatically exited. The display can be programmed to automatically enter or exit the MONitor mode based on elapsed time or movement of the encoder. If the programmable auto monitor is enabled (Programming parameter Pr19 set to 1), the Digital Display will automatically enter monitor mode after either 30 or 60 seconds of no encoder motion. If the programmable auto monitor is disabled, the ProScale will automatically exit monitor mode if the encoder is moved beyond a programmable distance from the monitored position. This option, in conjunction with auto monitor activation, allows the ProScale to be kept in monitor mode without manually pressing the monitor key. (See Programming Parameters 19,20, 21. Factory default is OFF.) SEND The Digital Display provides an output port that can be used to send measurement information to a compatible SPC device such as a printer or data acquisition unit. After connecting the SPC device to the 10 pin connector on the display, the user may initiate the data transmission by momentarily pressing the SEND key. This signals the SPC device to acquire the data from the digital display. Pressing the SEND key displays “ Snd ” on the display for 1 second to show activation of the send function (even if no SPC device is attached to the ProScale). The data format and connector style of the ProScale SPC output is the same as Mitutoyo SPC. This is an industry standard that can be interfaced with most available SPC products including multiplexers, RS232 converters and PC plug-in boards. Data from the ProScale is sent to the SPC connector in either millimeters or decimal inches, whichever is currently displayed on the LCD. If no SPC device is attached to the display, the SEND key has no other function. See Section 6 Accessories for interface and data acquisition products descriptions. F1 / F2 These keys are used for special features and/or Custom programming functions.
ProScale M150, M250 and all products with General Purpose LCD Digital Displays 32 of 32 Programming Several functions of the digital display are user programmable. The following instructions describe what features are available and how to change the system’s factory defaults to customize the display for your application. The keys pictured have multiple functions. Timing, which is how long a key is depressed, and the combination of the keys pressed is important. This manual uses the term ‘”momentarily” to describe a key press of typically less than 1 second. Whereas “press and hold” is used imply a key press of typically longer than 1.5 seconds. As an example; when using a PC keyboard to type a CAPITAL letter you would “press and hold” the SHIFT key and “momentarily depress the appropriate letter key. The “function” associated with the key(s) pressed is executed on the key RELEASE, not the key DEPRESS. This is important since some keys execute different functions based on how long they are depressed. These key operations, once tried, quickly become intuitive. To enter programming mode, press and hold the MODE key and then momentarily press the 0 (zero) key. The MODE key must be held for approximately 1 second before the depression of the 0 (zero) key. Once you are in the Programming Mode, momentarily pressing the MODE key will advance through the Programming Parameter list. To step backwards in the Programming Parameter list press and hold the ON/OFF key and momentarily press the MODE key. Momentarily pressing the + (plus) key while displaying a Programming Parameter will increase the parameter setting. Momentarily pressing the - (minus) key while displaying a Programming Parameter will decrease the parameter setting. Momentarily pressing the 0 (zero) key while displaying a Programming Parameter will revert the parameter to its factory default setting. CAUTION: The Limit Mode (See Programming Parameters 14,15 16 17) functionality is still active even while the display is in programming mode. Changing LIMITS may result in the Limit/Monitor Signal hardware output becoming active immediately. To exit programming mode, press and hold the MODE key and then momentarily press the 0 (zero) key. NOTE: The display will automatically exit programming mode after 60 seconds of no key activity.
ProScale M150, M250 and all products with General Purpose LCD Digital Displays 33 of 33 Programming Parameters are listed below. Values in [ ] are the available range of values that can be programmed for that entry. Factory defaults are shown in bold. Pr0 – Encoder Direction [0,1] Change value to reverse the direction of measurement readings. Pr1 – Enable/Disable Segment Offset [0, 1] 0 = For ABSOLUTE scales shorter than 430mm, (16.9in). ALL Incremental scales 1 = For All ABSOLUTE scales longer than 430mm, (16.9in). Pr2 – High Speed Readhead [0, 1] 0 = Normal Readhead 1 = High Speed Readhead Use this setting only if instructed by special instructions included with High Speed Readheads. A setting of 1 will impact battery life. Pr3 – Enable/Disable the +, - and ZERO keys [0,1] 0 = Disables operation of Zero, + and – keys (Display will be in Lock Mode). 1 = Enables operation of Zero, + and – keys. Pr4 – Display Resolution [0, 1, or 2] Sets the displayed resolution in decimal mode. (No change in fractions mode.) 0 = Reduced resolution Inch = xxx.xx MM = xx.x 1 = Normal resolution Inch = xxx.xxx MM = xx.xx 2 = Increased resolution Inch = xx.xxxx MM = xx.xx (Inch mode only) Auto scaling will allow measurements of over 100 inches when in high resolution. Measurements over 100 inches will automatically be reduced to 3 decimal places. Pr5 – Metric Display Units [0, 1] Controls whether the measured value is displayed in millimeters or centimeters when in metric mode. 0 = millimeters 1 = centimeters Pr6 – Disable Fractions/Inches [0, 1, 2] 0 = All measurement modes (millimeters or centimeters, inches and fractions) 1 = No Fractions. Only decimal inches and metric units* will be displayed. 2 = Only Metric. No Imperial (decimal inches or fractions) will be displayed. * Pr5 will determine if mm or cm are displayed for metric units. Pr7 – Scaling Factor [.001 .. 99.999] Default = 1.000 (No Scaling.) The multiplier applied to the measurement. Scaling factors less than 1.000 will make the displayed measurement less that the actual measurement. Scaling factors greater than 1.000 will make the displayed measurement greater than the actual measurement.
