The HIGH judgement output is switched on if the measurement value is bigger
than the HIGH Threshold value.
The LOW judgement output is switched on if the meansurement value is
smaller than the LOW Threshold value.
The PASS judgement output is switched on if the measurement value is
between the the Low and Hi
g
h Threshold values.

6 Setup mode
Pressing and holding the “MENU/SET” button for 3 seconds changes the mode of the
amplifier to the setting mode (pressing again for 3s moves back to RUN mode):
Below you see the navigation through all menus (Details switched on, all other
options switched off) by pressing the left/right arrow button. You change the options
by pressing the up and down arrow buttons and confirm with the Menu/Set button:
MENU LED Indicates
setup mode
Press for 3 seconds
Selection of one of 4 banks.
Setup the response time. The
response time is determined by
the number of averages multiplied
with the cycle time of one
measurement.
Setup the High Threshold for the
digital outputs.
Setup the Low Threshold for the
digital outputs.

* Detail: These menus are only displayed if “Detail” is
switched “ON”

Setup the Hysteresis.
Setup the scale of the display and
analog output value. (All settings
(S1/S2) for the scaling are stored
in the bank data. See p. 11.)
Setup the Hold function. See p.
10.
Setup of the analog output either
voltage or current and the output
range.
Setup the behavior of the analog
output in the case that the sensor
is in error state (resp. not able to
obtain a measurement value.
Display: E-dark). See p. 12.
Setup the clamp value for the
analog output (only valid if
RStOUT is set to “Clamp”).

7 Smart Tuning
Smart Tuning sets the optimum parameters for the chosen response time (“Speed”
setting) and the measurement object automatically. The ZX2 has 3 different Smart
Tuning modes:
Single Smart Tuning:
Single Smart Tuning is used if the objects in the final application always have the
same surface characteristic. Place the measurement object in front of the sensor and
press the “Smart” button for 1s:
Multi Smart Tuning:
Multi Smart Tuning is used if there are a couple of different objects in the final
application which are varying in the surface characteristics. Place one after another
of the measurement objects in front of the sensor and press each time the “Smart”
button for 2s:
Active Smart Tuning:
Active Smart Tuning is used if the object(s) is (are) moving in the final application.
The Smart Active tuning is activated by pressing the Smart button for 5s then the
object(s) is (are) passed by in front of the sensor and finally the Smart button is again
pressed for 5s in order to stop the tuning process.
Press for 1 second
Press for 2 seconds
Press for 5 seconds

8 Hold (=trigger) functions
The hold function is used to hold a certain measurement value while a certain
sampling period. After the sampling period has passed this value is displayed and
applied at the analog output. The possible methods are “Average”, “Peak to Peak”
(=maximum-minimum), “Sample”, “Bottom” and “Peak”. The sampling period is
determined either by an external signal at the Timing Input (purple wire, and menu
setting “Ext-In” set to “TimRSt”) or by a period determined by the measurement value
while it is below or above a certain threshold level (setting “Trig” to “Self-Up” or “Self-
Dn” and the threshold level value under “Self-Level”).
The 5 different hold modes are:
If you have activated one of the HOLD functions and the digital “Timing” input you
can press the “up-arrow” key in “RUN” mode in order to simulate an active signal at
the timing input:
