4.5 Pressure sensors
DANGER!
Danger to life due to loss of explosion protection
Non-observance of these instructions and their contents may result in the
loss of explosion protection.
If third-party reference pressure sensors are used, they can damage the
hand-held pressure indicator and the reference pressure sensor.
▶
Only use model CPT62I0 reference pressure sensors!
▶
Only ever use the original connection cable from WIKA for the operation of
CPT62I0 reference pressure sensor.
4.5.1 Available pressure sensors
The hand-held has been designed so that all model CPT62I0 pressure sensors can
be connected without the need for any readjustment. A wide range of interchangeable
sensors is therefore available, with ranges of up to 1,000 bar (14,500 psi), see
10 “Specifications”.

4.5.2 Connecting/changing pressure sensors
CAUTION!
Damage to the instrument
For overpressure or gauge sensors, the pressure compensation vent hole is
found at the top of the sensor housing.
▶
This vent (with integrated diaphragm) must always remain clear!
Before switching the instrument on, connect the reference pressure sensor,
otherwise it may not be correctly identified by the instrument.
1. To connect or change the reference pressure sensor, switch off the instrument.
2. Connect the hand-held pressure indicator and the pressure sensor to each other
electrically using a separate sensor connection cable. Use the 7-pin plug contact on
the pressure sensor for this.
3. Connect the 7-pin connector to the reference pressure sensor in accordance with the
orientation guide and secure it through the connection sleeve.
Turn the connection sleeve clockwise without much force.
4. Connect the 6-pin M-DIN connector to the hand-held on CH1 or CH2 in accordance
with the orientation guide.
When connecting the sensor connection cable to the hand-held, the pressure sensor's
connector might not locate properly in the socket. In this case you should try holding the
connector by the bend protection, rather than by the connector sleeve.
▶
Connect the connector without tilt the threads.
⇒
If the connector is positioned correctly, it can be plugged in without any significant
effort.
▶
When removing the pressure sensor, do not pull on the sensor connection cable, but
only on the connector sleeve.
4.6 Serial or analogue interface
DANGER!
Danger to life due to loss of explosion protection
Non-observance of these instructions and their contents may result in the
loss of explosion protection.
Through working in flammable atmospheres, there is a risk of explosion

6.4.1 Pressure units (unit)
Depending on the measuring range of the current pressure sensor, the pressure value
can be displayed in any one of the following units: mbar, bar, Pa, kPa, MPa, mmHg, inHg
or psi.
6.4.2 Sea-level (SL) and altitude (Alti) correction for absolute pressure sensor
With a connected absolute pressure sensor, the instrument measures absolute pressure.
This is not to be confused with the “air pressure at sea level” given by the weather station.
With this pressure indication, the altitude-dependent atmospheric pressure drop is
calculated. The instrument is capable of making this air pressure altitude correction.
Setting of “SL” and “Alti”
1. Press the [SET/MENU] button for 2 seconds.
⇒
The main menu “SEt” is accessed.
2. With the [TARA] button, select the “SL” parameters.
3. With the [MIN] or [MAX] buttons, activate the “SL” parameter.
4. With the [STORE/QUIT] button, confirm the entry.
5. With the [TARA] button, select the “Alti” parameters.
6. With the [MIN] or [MAX] buttons, enter the altitude.
7. With the [STORE/QUIT] button, confirm the entry.
8. Press the [SET/MENU] button.
⇒
Return to main menu.
The setting is only possible, if an absolute pressure sensor is connected to
sensor connection 1.
When the “Sea Level” function is activated, the arrow for 'SL' is indicated below in the
display. Once the altitude of the fixed location above sea level has been entered, the
instrument displays the absolute pressure at sea level.

6. Commissioning, operation
When two absolute pressure sensors are connected, the “Sea Level” function
for both pressure sensors corresponds to the setting of pressure sensor 1.
6.4.3 Measurement types (rAtE)
The instrument supports three different measurement types for various purposes. Two of
these operate with an increased measuring rate of > 1,000 measurements/s.
6.4.3.1 Standard measurement (rAtE-SLo)
The measuring rate is 4 Hz. The averaging and filter functions are active.
Application range
■
Measurement of slowly changing or static pressures, e.g. calibration, leak testing,
atmospheric pressure measurement,
■
Highest measurement accuracy, insensitive to disturbances, low power consumption.
6.4.3.2 Peak value detection (rAtE-P.dEt)
The measuring rate is > 1,000 Hz and the measuring signal is displayed unfiltered.
Field of application in combination with logger function
■
Measurement of pressure spikes or fluctuating pressures with a resolution of < 1 ms.
■
The cyclic logger function records the arithmetic mean value, the highest and the
lowest pressure during the chosen time interval.
In this setting, there is an increased power consumption and the
measurement is susceptible to interference (also electromagnetic
interference).
6.4.3.3 Fast measurement = Fast (rAtE-FASt)
The measuring rate is > 1,000 Hz and the measuring signal is displayed filtered. As a
result, it is less sensitive to interference and the short-term spikes are filtered out. Other
than that, this function is identical to “rAtE-P.dEt”.

WIKA operating instructions, model CPH62I0
EN
11221801.04 10/2018 EN/DE
6. Commissioning, operation
6.4.4 Averaging
The averaging function acts on the displayed values (display and interface). It is
completely independent of the averaging within the logger function (do not confuse
them!).
The averaging integrates the measured values during a chosen time interval and then
calculates the average display value.
The function is independent of the selected measuring rate (fast/slow measurement).
So long as a sufficiently long set time (in seconds) has not yet been measured in
order to calculate the mean value, “----” is shown in the display - in the lower display, a
'countdown' is displayed.
During the low-power logger operation, the averaging function is always deactivated.
Function of Min./Max. value memory in conjunction with the averaging function:
■
If averaging is activated and slow measurement, “rAtE-SLo”, is selected, the Min./
Max. memory value relates to the average display values.
■
If averaging is activated and fast measuring function is selected (“rAtE-FASt” or
“rAtE-P.dEt”), the Min./Max. memory value relates to the internal measured values (>
1,000 Hz measuring rate).
6.4.5 Zero point correction sensor 1 (OFS.1) or sensor 2 (OFS.2)
A zero point offset can be carried out for the respective measurement:
Displayed value = measured value – offset
Default setting
'off' = 0.0, i.e. no correction is made. The zero point correction, together with the slope
correction, is mainly used for the adjustment of sensor deviations. The entry is made in
the display unit.
6.4.6 Scale correction sensor 1 (SCL.1) and sensor 2 (SCL.2)
The scale of the corresponding measurement can be influenced by this factor (factor is in
%):
Displayed value = (measured value – offset) * (1+Scal/100)
Default setting
'off' = 0.000, i.e. no correction is made. The scale correction, together with the zero point
correction, is mainly used for the adjustment of sensor deviations.

If no button is pressed and no serial communication occurs during the switch-off delay,
the instrument will automatically switch itself off. The switch-off delay can be set between
1 and 120 min. If “P.oFF” = “oFF” then the power-off function is deactivated.
