Intended Use
The temperature compensated Capacitance Diaphragm Gauges
of the Stripe CDG045Dhs series are intended for absolute
pressure measurement of gases in their respective pressure
ranges (→ 3).
Ideally the measurement values can be read out digitally via
EtherCAT interface or analog. The gauges can also be operated
in connection with an INFICON Vacuum Gauge Controller (VGC
series) or another appropriate controller.
Functional Principle
A ceramic diaphragm is deflected by pressure. The deflection is
measured capacitively and converted into a digital or into an
analog linear output signal by the digital electronics. The digital
output signal can only be read out via the EthreCAT interface.
The output signal is independent of the gas type.
Very accurate pressure measurement is achieved by heating the
sensor to a constant temperature of 45°C which results in a compensation of changes in the ambient conditions and a reduced
deposition of process products and by-products in process applications.

4.2 Zeroing the Gauge
The gauge is factory calibrated while "standing upright"
(→ "Calibration Test Report").
Perform a zero adjustment, when the gauge is operated
for the first time.
Due to long time operation or contamination, a zero drift could
occur and zero adjustment may become necessary.
For adjusting the zero, operate the gauge under the same constant ambient conditions and in the same mounting orientation
as normally.
The output signal (measuring signal) is depending on the mounting orientation. The signal difference between the vertical and
horizontal mounting orientation is:
4.2.1 <ZERO> Adjustm ent
F.S. ΔU / 90°
1000 Torr/mbar ≈2 mV
100 Torr/mbar ≈10 mV
10 Torr/mbar ≈50 mV
1 Torr/mbar ≈300 mV
0.1 Torr/mbar ≈1.8 V
≤0.05 Torr/mbar
only standing upright mounting
orientation
If the gauge is operated via a controller, the zero of the
whole measuring system has to be adjusted on the
controller: first, adjust the zero of the gauge and then,
the zero of the controller.
The zero can be adjusted via
• the <ZERO> button on the gauge,
• the diagnostic port (→ [4]),
• the EtherCAT interface (→ [3]),
24
tina84e1 (2014-07)
• the digital input "Remote Zero" (briefly apply the
supply voltage to pin 10),
• an INFICON Vacuum Gauge Controller (VGC series).
While the gauge is being heated and/or under atmos-
pheric pressure, the zeroing function is locked in order
for operating errors to be prevented.
Evacuate the gauge to a pressure according to the table
below:
F.S.
1100 mbar
1000 Torr
500 Torr/mbar
200 Torr/mbar
100 Torr/mbar
50 Torr/mbar

1 Torr/mbar
0.5 Torr/mbar
0.25 Torr/mbar
0.1 Torr/mbar
0.05 Torr/mbar
0.02 Torr/mbar
0.01 Torr
If the final pressure is too high for zero adjustment (>25%
of the F.S.), the zero cannot be reached and the
<STATUS> LED blinks green. If this is the case, activate
the factory setting and adjust the zero again (→ 34).

Operate the gauge for at least 2 hours (until the signal is
stable).
tina84e1 (2014-07) 25
Briefly press the <ZERO> button with a pin (max.
ø1.1 mm). The zero adjustment runs automatically. The
<STATUS> LED blinks until the adjustment (duration ≤8 s)
is completed.
Press the
button briefly
max. ø1.1 mm
After zero adjustment, the gauge automatically returns
to the measurement mode.
The <STATUS> LED blinks green if
• the signal output is negative (< -20 mV) when the final pressure has been attained
• the zero adjustment has failed.
4.2.2 <ZERO> Adjustment with Ramp Functi on
The ramp function allows to adjust the pressure value at a
known reference pressure within the measurement range of the
gauge.
It also permits to adjust an offset of the characteristic curve in
order to
• compensate for the offset of the measuring system or
• obtain a slightly positive zero for a 0 … 10 V AD converter.
The offset should not exceed 5% of the F.S. (+500 mV). At a
higher positive offset, the upper limit of the measurement range
is exceeded.
26
tina84e1 (2014-07)
Zero adjustment using the ramp function can be
performed via
• the <ZERO> button on the gauge,
• the EtherCAT interface (→ [3]),
• the diagnostic port (→ [4]),
Recommended procedure for adjusting the offset of a
measuring system: → Notice 24.
Operate the gauge for at least 2 hours (until the signal is
stable).
Push the <ZERO> button with a pin (max. ø1.1 mm) and
keep it depressed. The <STATUS> LED starts blinking.
After 5 s, the zero adjustment value, starting at the current
output value, keeps continually changing (ramp) until the
button is released or until the setting limit (max. 25% F.S.)
is reached. The corresponding output signal is delayed by
about 1 s.
Keep the button
depressed
max. ø1.1 mm
tina84e1 (2014-07) 27
Push the <ZERO> button again:
Fine adjustment
within 0...3 s:
the zero adjustment value changes
by one unit (push <ZERO> button in
intervals of 1 s)
Change of direction
within 3...5 s:
the zero adjustment changes its
direction (the blinking frequency of
the <STATUS> LED changes
briefly)
If the <ZERO> button is released for more than 5 s, the
gauge returns to the measurement mode.
The <STATUS> LED blinks green if the signal output is negative
(< -20 mV).
4.3 Switching Functions SP1, SP2
The two switching functions can be set to any pressure within
the measurement range of the gauge. A solid state relay is
provided for each switching function.
The current threshold setting
• is output at the measurement signal output instead of the
pressure signal and can be measured with a voltmeter after
the <SP1> or <SP2> button is pressed
• can be read / written via the diagnostic port (→ [4]) and the
EtherCAT interface (→ [3]).
Switching characteristics and hysteresis
The switching characteristics and the hysteresis of each
set point can only be programmed via the diagnostic
port (→ [4]) and the EtherCAT interface (→ [3]).

DANGER: malfunction
If processes are controlled via the signal output,
keep in mind that by pushing an <SP> button the
measurement signal is suppressed and the corresponding threshold value is output instead. This
can cause malfunctions.
Push the <SP> button only if you are sure that no
malfunction will cause.
The setpoints can be adjusted via
• the buttons on the gauge,
• the diagnostic port (→ [4])
• the EtherCAT interface (→ [3]).
Adjusting Setpoint <1>
Push the <SP> button with a pin (max. ø1.1 mm). The
gauge changes to the switching function mode and outputs
the current threshold value at the measurement value
output for about 10 s (LED <1> blinks).

The factory setting of the reset value is 1% F.S. above
the Low Trip Point and 1% F.S. below the High Trip
Point (hysteresis).
If after programming of the hysteresis the button <SP> is
pushed, the factory setting of the hysteresis (1%) is
reactivated.

4.5 ATM Setpoint
The setpoints SP1 and SP2 of gauges with separate atmospheric pressure sensor
pressure setpoint (ATM setpoint) via the diagnostic port or the
EtherCAT interface.
The ATM setpoint is defined as a factor of the current atmospheric pressure. The relay switches when the pressure in the
vacuum system has reached the defined value (differential
pressure in relation to the atmospheric pressure).
Example: ATM setpoint: 110% of the atmospheric pressure
(= factor 1.1)

Loading of the default parameters is irreversible.
Loading the default parameters:
Put the gauge out of operation.
Keep the <ZERO> button depressed for at least 5 s while
the gauge is being put into operation (Power ON).
4.7 Diagnostic Port (USB Interface)
The diagnostic port <DIAG> permits to output the pressure
reading and all status information and to enter all settings at the
same time (→ [4]). A standard USB cable type A/mini B can
be used.
Required software: T-Gauge. Please contact your local INFICON
service center.

4.8 EtherCAT Operation
Caution
Caution: data transmission errors
Any attempt to simultaneously operate the gauge
via the EtherCAT interface and the diagnostic port
causes data transmission errors.
Therefore the gauge must not be operated simultaneously via the EtherCAT interface and the diagnostic port.
For operating the gauge via EtherCAT, prior installation of the
device specific ESI file is required on the bus master side. This
file can be downloaded from our website.
