but rather only on the connector body.
4.5 Power supply
The internal Lithium-Ion battery, which can be easily charged with the battery charger
supplied with the equipment, serves as the power supply for the instrument.
The instrument is delivered with a charge level of 25 ... 50 % and should be fully charged
once before being used.
The battery-level display is shown in the upper right of the screen (see chapter "4.6
Explanation of display and keypad").
GB
When the mains lead/battery charger is connected to the CPH6400, the
battery will be charged, even if the CPH6400 is switched o.
CAUTION!
The battery level during storage or shipping should be between 25 ... 50 %.
■
When the battery charger is no longer being used, the mains plug should be discon-
nected from the mains socket. Do not leave the battery charger connected to the
rechargeable battery for longer than one day, since overloading can shorten its service
life.
■
Should the rechargeable battery still not be fully charged after 24 hours, contact the
manufacturer. When not being used, a fully-charged battery will lose its charge over
time.
■
Extreme temperatures have an adverse eect on battery charging. As a result, the
battery may rst need to be either cooled or warmed, as appropriate.

1. Wrap the precision hand-held pressure indicator in an antistatic plastic lm.
2. Place the precision hand-held pressure indicator, along with shock-absorbent material,
in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.
WARNING!
Before storing the precision hand-held pressure indicator, the reference
pressure sensors or temperature sensors (following operation), remove
any residual media. This is of particular importance if the medium is
hazardous to health, e.g. caustic, toxic, carcinogenic, radioactive, etc.

6.1 Requirements for test assemblies with the CPH6400
GB
Initially the test assembly must be physically assembled and connected electrically (see
chapter "4.4.1 Connection of the model CPT6400 reference pressure sensor").
Before switching the CPH6400 on, ensure that the test assembly is not pressurised
(system is vented to atmosphere) and that the equipment is correctly assembled and in
the correct mounting position.
Particularly small measuring ranges (e.g. < 1 bar) are orientation dependent (i.e. the
mounting position considerably inuences the measurement signal). This can be
compensated, if necessary, using the TARE function (see chapter "6.5 TARE function").
Absolute-pressure measuring ranges < 1 bar absolute are, by denition, in an overload
condition at atmospheric pressure. Therefore the message "Sensor Overow" appears in
the display, indicating a pressure outside of the measuring range of the attached sensor.
If the pressure is reduced, so that it falls within the permissible measuring range, then this
message disappears from the display.
Before starting any task, the device should be switched on briey to
determine that there is sucient charge in the battery (battery level in %).
The battery level is shown in the upper right of the screen in a devicestatus message. 100 % battery charge will enable approximately 25
hours of instrument operation.
Only disconnect test and calibration installations once the system has
been depressurised!
6.2 Instrument features
The precision hand-held pressure indicator features 3 operating modes:
■
MEASURING MODE without additional function (standard measuring mode)
■
MEASURING MODE with MIN and MAX function
■
MEASURING MODE with display of the pressure rate (with 2-channel version with
additional display of temperature)

These dierent measuring modes are accessible via the MODE key.
Via the UNIT key, the current unit of pressure can easily be changed to one of the seven
stored pressure units and the display resolution matched accordingly via the FUNC key.
The integrated data logger can be operated via the FUNC key and uploaded and
displayed using the WIKA "PrintCal" PC software. In addition, "PrintCal" enables computer-assisted calibration of pressure measuring instruments including the generation of
calibration certicates.
For data transfer to a PC the model CPH6400 precision hand-held pressure indicator
features a USB interface, which is activated and deactivated via the FUNC key.

6.4 Measuring modes
6.4.1 Standard measuring mode
Approx. 3 seconds after switching on the CPH6400, with the CPT6400 reference
pressure sensor connected correctly, the "Standard measuring mode" display appears
GB
(see gure below). It displays the current measured value, the unit and pressure type of
the currently-connected pressure sensor and additionally a bar graph and the charge
level of the rechargeable battery.
If the sensor has not been calibrated with the indicator, the message
"Uncalibrated Sensor" will appear on the display. Use of the sensor is
thus not permitted.
