4. Design and function
In order to make the electrical connection for a CPT6400 reference pressure sensor, bring
together the corresponding cable plug connector to the sensor in line with the orientation
guide and secure it using a connection sleeve (screw in the connection sleeve clockwise
without too much force). To loosen the connection, the connection sleeve must be turned
anti-clockwise. To disconnect the sensor do not pull the cable, but rather only on the
connector body.
For the connection to the digital indicator, the other end of the cable must also be brought
together in line with the orientation guide and secured using the connection sleeve (screw
in the connection sleeve without too much force). To loosen the connection, the connec-
tion sleeve must be turned anti-clockwise. To disconnect the sensor do not pull the cable,
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").
When the mains lead/battery charger is connected to the CPH6400, the
battery will be charged, even if the CPH6400 is switched off.
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 effect on battery charging. As a result, the
battery may first need to be either cooled or warmed, as appropriate.
