ZX-T Operation Manual 89 Section 5 DETAILED SETTINGS Calculating Measured Values This section describes the setting procedure that is used to calculate measured values when Calculating Units are connected by Amplifier Units. Up to 8 Amplifier Units can be used at one time, and measured values can be calculated even when Sensors have different measurement distances. The ZX-L-series Smart Sensors (Laser Type), ZX-E-series Smart Sensors (Linear Proximity Type), and ZX-W-series Smart Sensors (Microwave Type) are not compatible. Set the expression using an Amplifier Unit starting at CH2. CH1 Calculating Unit Expression setting CH2 Calculation result output Section 5 Calculating Measured Values A+B A-B Note: Expression setting CH3 Calculation result output Expression setting CH8 Calculation result output The 2 types of expressions are outlined in the following table. Expression type Description Finds the sum of the measurement results for two Amplifier Units. Finds the difference between the measurement results for two Amplifier Units. Application (See note. ) · Measuring thickness · Measuring reference surfaces and gaps · Measuring height difference · Measuring flatness (See note. ) A: Amplifier Unit in which the expression is set (CH2 to CH8) B: CH1 Amplifier Unit The response time for CH2 Amplifier Units to which expressions have been set is increased by 1. 0 ms. The response time is also influenced by the setting for the number of samples to average, so the response time will be the response time based on the set number of samples to average +1. 0 ms. Setting Number of Samples to Average, p. 70 90 ZX-T Operation Manual Section 5 DETAILED SETTINGS Finding the Height Difference Use the expression A - B. Perform the setting at all Amplifier Units starting from the one at CH2. The following describes the procedure for finding the height difference using the CH2 Amplifier Unit as the example. CH1=B CH2=A Moving to FUN and CALC 1. Set the mode switch to FUN on the CH2 Amplifier Unit. Section 5 Calculating Measured Values 2. Use the LEFT and RIGHT Keys to display CALC on the main display. Selecting Expressions 3. Press the UP or DOWN Key. The sub-display will flash. 4. Use the UP and DOWN Keys to select the expression type. 5. Press the ENT Key to confirm the selection. The expression will be registered. ZX-T Operation Manual 91 Section 5 DETAILED SETTINGS Using the Zero Reset Function 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 RUN mode, the measured value can be reset to 0 at any timing during measurement. Example 1: Using the Height of the Sensing Object as the Reference Value and the Tolerance Output as the Measured Value -0. 2 (LOW threshold) Reference value Sensing object +0. 2 (HIGH threshold) Section 5 Using the Zero Reset Function Example 2: Measuring Height Differences on Sensing Objects (Zero Reset at Each Measurement) Measures this step. Zero reset Zero reset Operation Zero reset When resetting to zero for each measurement, change the settings so the zero reset level is not saved. p. 96 You can set any offset value when you want to set a non-zero measured value. 92 ZX-T Operation Manual Section 5 DETAILED SETTINGS Example: Measuring the Height Difference of the Sensing Object for Reference (Setting 1. 0 for the offset value) -1. 2 (LOW threshold) (Reference value) 1. 0 Sensing object 1. 2 (HIGH threshold) Section 5 Using the Zero Reset Function ZX-T Operation Manual 93 Section 5 DETAILED SETTINGS Setting Offset Values Set an offset value when the reference value for zero reset is a value other than 0. Moving to FUN and ZRDSP 1. Use the LEFT and RIGHT Keys to display ZRDSP on the main display. POWER ZERO ENABLE (mm) Setting Offset Values 3. Press the UP or DOWN Key. The leftmost digit of the sub-display will flash. SUB Section 5 Using the Zero Reset Function 4. Use the Cursor Keys to set the offset value. Press the ENT Key to confirm the setting. The offset value will be registered. Move between digits. Increment and decrement the numeric value. SUB 94 ZX-T Operation Manual Section 5 DETAILED SETTINGS Executing Zero Reset When the zero reset function is used, the measured value can be reset to a reference value of 0 when the ENT key is pressed or an external signal is input. If zero reset has already been executed, that value will be overwritten. [. . . ] Page 86: Values on display illustrations changed. Page 119: Model number added to heading.
