10.Using the ALMEMO®500
The following chapters provide information regarding the use of the data logger
ALMEMO®500 and a detailed description of the data loggers’ functions.
10.1. Connecting the power supply
The data logger is powered with a supply voltage of 12 V DC. The power is supplied
by an included mains unit (article: ZB1212NA10, 12 V DC, 2A). Alternatively, the
power can also be supplied by an optionally available rechargeable battery pack. You
will find a detailed description regarding the power supply in chapter 8.3. Connect the
mains unit to the DC connector (14).

- 18 -
10.2. Connect sensors
Connect the required ALMEMO®sensors to the ALMEMO®input sockets M0 to M9
of your measuring instrument and make sure that the two locking levers engage
correctly (for removing the plug, press the two levers on the sides).
Sensors may only be connected and disconnected when the device has been
switched off.
All ALMEMO®sensor generations (V5, V6 sensors, as well as D6 and D7 digital
sensors) can be arbitrarily connected to the ALMEMO®input sockets. The
comprehensive ALMEMO®sensor program and the option to connect your own
sensors to ALMEMO®devices is described in detail in the ALMEMO®Manual (see
ALMEMO®Manual chapter 3 and chapter 4).
All standard sensors with ALMEMO®plugs are generally programmed with
measuring range and dimension and can therefore readily be connected to every input
socket.
10.2.1. Measuring inputs and auxiliary channels
In the standard configuration, the measuring instrument ALMEMO®500 features 20
input sockets (per measuring circuit board M0 to M9) to which primarily the
measuring channels M000_0 to M009_0 (measuring circuit board 1) and M010_0 to
M019_0 (measuring circuit board 2) are allocated.
Since standard sensors (V5, V6, D6, and D7) can offer –if needed –up to 4 channels
and D7 sensors even a maximum of 10 channels, the channel assignment displayed in
Figure 4 results. In this case, the allocation of V5 and D7 sensors to the input sockets
is exemplarily illustrated.
