4 Design and Function
4.1 Short description / Description
The CPH65I0-S1/S2 intrinsically safe hand-held pressure calibrator is designed to be a simple to
use yet very versatile pressure calibrator. Its two internal pressure sensors combined with inputs
for mA, switch contacts and an RTD probe allow the CPH65I0-S1/S2 intrinsically safe hand-held
pressure calibrator to calibrate virtually any pressure device.
The CPH65I0-S1 intrinsically safe hand-held pressure calibrator is a single sensor pressure
calibrator; the CPH65I0-S2 intrinsically safe hand-held pressure calibrator is a dual sensor
pressure calibrator. The CPH65I0-S1 uses the P1 port for all pressure inputs. The P2 port is only
used on the CPH65I0-S2. Therefore on the CPH65I0-S1, all menu choices involving pressure are
limited to the P1 port only. All other CPH65I0-S1 features and functions are the same as for the
CPH65I0-S2.

WIKA Operating Instruction, Model CPH65I0 17
GB
6 Commissioning, operation
6.1 Commissioning
When the calibrator is turned on by pressing the ON/OFF key, it will go through a
short startup self-check routine. During that routine, the display shows the current
firmware revision level, auto shutdown status and the ranges of the internal pressure
sensors. The calibrator requires a maximum of 5 minutes warm-up to rated
accuracy. Large changes in ambient temperature may require a longer warm-up
period. See chapter 6.4 for instructions on zeroing the pressure sensor displays.
Pressure ranges should be zeroed each time the calibrator is started.
6.2 Calibrator display
The calibrator display consists of two regions: The menu bar (located along the bottom of the
screen) is used to access a menu system. The main display (the rest) consists of up to three
process measurement sub-regions. These sub-regions will henceforth be referred to as the
UPPER, MIDDLE and LOWER displays. The following figure and table show the location of the
different display fields and a description.
1) Primary parameters

6.2.1 Main menu functionality
There are three options on the main menu, “CONFIG”, {active display} and “MORE”. The main
menu is home for the menu display.
6.2.1.1 Setting the active display
The active display is indicated by the center option on the main menu, pressing the F2 key will
toggle the active display.
6.2.1.2 Setting active display parameters
To set the parameters of the active display use the “CONFIG” option to get to the display
configuration menu.
Here the “SELECT” option will toggle through the choices for each parameter. The first parameter
is “MODE”. Since current and switch test modes all use the same jacks, two of these functions
cannot be used concurrently. The ability to select certain functions is limited based on what is
already selected in another active display. The “NEXT” option is used to change to the second
parameter. Only RTD (resistance thermometer) and pressure modes have a second parameter,
RTDs can be read in Celsius or Fahrenheit and pressures can be read in 17 engineering units.
Within any single display sector, the following modes are available:
P[1] = pressure on left side sensor
P[2] = pressure on right side sensor
P[1] ST = switch test with left side sensor
P[2] ST = switch test with right side sensor
mA = current measurement
RTD = resistance thermometer measurement (in the event a resistance thermometer is connected)
The following table shows which functions are available concurrently.
An “--“ in a column indicates that the mode in the active display will not be available for selection if
the mode in that row is in use in any other active display.

6.3 Using the backlighting
The backlight is controlled by the dedicated backlight key. It toggles on and off when the key is
pressed; this is one of the few functions that cannot be controlled by the serial interface. There are
no user configuration settings for the backlight.
6.4 Using the "ZERO" function
When the “ZERO” key is pressed, the calibrator will zero the active display if 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.
6.4.1 Internal relative pressure sensor
When a sensor is selected on the active display and the “ZERO” key is pressed the calibrator
subtracts the current reading from the output. 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.
6.4.2 Internal absolute pressure sensor
When an absolute sensor is selected on the active display and the “ZERO” key is pressed, the
calibrator prompts the user to either set or default the pressure reference.
If the set option is selected, the calibrator prompts the user to enter the barometric reference
pressure. This is done using the arrow keys (F2 and F3 keys). The sensor port should be open
(vented) to atmosphere while performing this procedure.
