4.1 Description
The model CPH65I0-S1/S2 intrinsically-safe hand-held pressure calibrator has been
designed so that it is simple to handle, but is also a very versatile pressure calibrator.
The two internal reference pressure sensors, combined with current input, pressure
switch function and a resistance thermometer, enable the CPH65I0-S1/S2 to calibrate
practically any pressure instrument.
The model CPH65I0-S1 intrinsically-safe hand-held pressure calibrator has a single
integrated pressure sensor; the model CPH65I0-S2 intrinsically-safe hand-held
pressure calibrator has two integrated pressure sensors. The CPH65I0-S1 uses
connection P1 for all pressure measurements. Connection P2 is only used in the
CPH65I0-S2. Thus, the pressure-related menu selection for the CPH65I0-S1 is limited
to connection P1 only. All other CPH65I0-S1 features and functions are identical to the
CPH65I0-S2.

6. Commissioning, operation
6. Commissioning, operation
As soon as the model CPH65I0 hand-held pressure calibrator is turned on, by pressing
the ON/OFF key, it will go through a short self-test routine. During this routine, the
display shows the current rmware version, auto-shutdown status and the measuring
range of the internal pressure sensor. The calibrator requires a maximum of 5 minutes
warm-up to reach its specied accuracy. Large changes in ambient temperature may
make a longer warm-up period necessary. The pressure display of the calibrator should
be zeroed before starting the pressure calibration. See chapter 6.3 "Use of the "ZERO"
function".
6.1 Calibrator display
The calibrator's display consists of two sectors: The menu bar (located along the
bottom of the screen) is used to access the menu system. The main display (the rest of
the display) consists of up to three sub-sectors for the measurement activities. These
sub-sectors will be referred to as the UPPER, MIDDLE and LOWER displays in this
document.
Figure 1 shows the location of the dierent display elds, which are described in the
following table.

6.1.1 Main menu Functionality
There are three options in this menu: "CONFIG", {active display} and "MORE". The
main menu is the home menu for the menu display.
GB
6.1.1.1 Setting the {active display} parameters
The {active display} is displayed via the middle option in the menu in the main display.
Pressing the F2 key switches between the {active display}.
6.1.1.2 Setting the {active display} parameters
In order to set the {active display} parameters, select the "CONFIG" option and open
the conguration menu.
The "SELECT" option switches between the available choices for each parameter.
Since voltage, current and switch-test modes all use the same leads, two of these
functions cannot be used concurrently. The ability to select certain functions is limited
and dependent upon what is already selected in the other display sector. The "NEXT"
option is used to switch to the second parameter.
Only the resistance thermometer and pressure modes have a second parameter.
Resistance thermometers can be displayed in Celsius or Fahrenheit and for pressure
there are 16 dierent units.
Within any single display sector, the following modes are available:
P[1] = left integrated pressure sensor
P[2] = right integrated pressure sensor (only for CPH65I0-S2)
P[1] ST = switch test with left integrated sensor.
P[2] ST = switch test with right integrated sensor (only for CPH65I0-S2)
mA measurement = current measurement
RTD = resistance thermometer (in the event a resistance thermometer
is connected)

6.3 Using the "ZERO" function
When the ZERO key is pressed, the calibrator will zero the {active display}, as long as
a pressure mode is selected and the pressure is within the zero limit. The zero limits are
within 5 % of the full scale range of the selected sensor. If the display indicates "OL" the
zero function will not operate.
The ZERO key is only used for pressure.

6.3.1 Internal relative pressure sensor
When a relative pressure sensor is selected in the {active display} and the ZERO key
is pressed, the calibrator subtracts the current displayed reading from the output value.
The zero limits are within 5 % of the full scale range of the selected sensor. If the display
GB
indicates "OL" the zero function will not operate.
6.3.2 Internal absolute pressure sensor
If an absolute pressure sensor is selected in the {active display} and the ZERO button
is pressed, the calibrator instructs the user to enter the reference pressure value with
"SET" or to reset with "DEFAULT". The reference instrument should be at least four
times as accurate as the absolute pressure sensor of the CPH65I0.
If "SET" is selected, the calibrator prompts the user to enter the barometric reference
pressure. The arrow keys, F2 and F3, can be used for this. The sensor connection
should be open (vented) to atmosphere while performing this procedure.
If, alternatively, "DEFAULT" is selected, the reversion to the factory setting must be
accepted with "CONFIRM" or the action aborted with "CANCEL".

6.4 Further menu controlled functions
There are ten submenus that can be accessed through the "MORE" option of the main
menu. A submenu contains three options. The rst option is unique to this function. The
second and third options of a submenu are always the same.
The "NEXT" option leads to the next submenu and the "DONE" option returns one to
the home menu.
With the last submenu the "NEXT" option returns to the home menu. The detailed menu
structure can be seen in 6.6 "Menu structure".
Note on naming:
If a 'Submenu' has further subdivisions, from now on it will be referred to as {function}
main menu. The "CONTRAST" submenu, for example, will be referred to as the
"CONTRAST" main menu. Otherwise it will be referred to as the {function} menu.
6.4.1 Setting the contrast
From the CONTRAST main menu, choose the "CONTRAST" option in order to access
the "Setting the contrast" menu.
