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.

(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.

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.

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.

You can set any offset value when you want to set a non-zero measured value.

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.
