3 Safety Notes
→The measuring modules are – depending on the type – able to measure
voltages, currents and powers for potentials above 50V. During operation
and especially when connecting the measuring module and the socket
adapter, make sure that you do not touch any high voltage components.
→For the connection of the measuring modules for AC/DC signals and for the
connection of the socket adapter, use the supplied or equivalent touch-
protected connection cables.
→The measuring module for DC signals must only be used for direct voltage
respectively direct current according to the measuring range indicated on
the type plate.
→Be particularly careful that the current modules are always connected in
series to the consumer i.e. in an input lead, and that they must not be
directly connected to the voltage source. When using the socket adapter, the
corresponding sockets of the socket adapter and measuring module (A-A ,
V-V, COM-COM) must be connected to each other. The color of the sockets
must be observed here.
→Never use the measuring device or the measuring module in wet or damp
environments.
→Keep the plastic housing away from open fire and hot surfaces (e.g.
burners).
→The measuring module and the socket adapter must no longer be used if
they are externally damaged or possibly no longer function after incorrect
connection.
→In case the measuring module or the socket adapter was used for purposes
other than intended or was used incorrectly, we cannot accept any liability
for any damages caused as a result.
→The protective function of the measuring module and socket adapter is
impaired if the devices are used in a manner not specified by the
manufacturer.

3 Safety Notes
- 6 –
→The measuring modul internal current measurement path is not intended for
continuous operation for currents greater than 10A. In that case, the
measurement can only be run for a maximum of 10 minutes. After this
period of time, the device must be cooled down to ambient temperature.
→Only use the socket adapter for the duration of the actual measurement.
3.1 Intended Use
The fast ALMEMO® measuring module for voltage, current, and power is intended

4.2 Description
The ALMEMO® AC measuring modules ZED7 30-ABx, ZED7 31-ABy, and
ZED7 37-ABxy measure the true root mean square (RMS) value of an AC current
signal and / or an AC voltage signal. This means that the measuring signal with
any arbitrary shape of curve is digitized at 1kHz and the true RMS value is
calculated and displayed on the measuring device.
Measuring modules of the ZED7 37-ABxy types measure the AC current as well as
the voltage synchronously and on the basis of these values, the active power and
the power factor are determined. The data transmission to the measuring device is
done digitally.
The measuring module is galvanically isolated at 6 kV and protected from
overvoltage. The measuring module can be connected to every measuring input of
any ALMEMO® measuring device of the device generation V7. It is also possible to
connect several measuring modules to one measuring device.
The power supply of the measuring module is provided by the ALMEMO®
measuring device via a DC/DC converter (isolation voltage 6 kV). The power
supply of the measuring device is stressed by approx. 40 mA, i.e. for a long-term
operation a mains adapter is required.
True RMS value measurement
The alternating voltage signal is permanently sampled at 1kHz and the total RMS
value of DC and AC voltage components is being calculated.

4.4 Description socket adapter
The socket adapter with order number ZE 2000-PA is optionally available. It is
intended as a safe tool for measuring voltage, current and power on circuits
electrically connected directly to the low-voltage network (CAT II). For safety
reasons, the short-circuit plug can only be connected to the black socket (COM)
and the blue socket (A) and is only used if no current measurement is required and
the circuit is only to be closed.
4.5 Digital ALMEMO® D7 measuring sensor
Building on the already self-sufficient ALMEMO®-D6 connectors with serial
interface, the possibilities of independence from the measuring device have been
consistently further developed and a completely new V7 measuring system has
been created. Efficient measurement of fast and slow probes with any range of
measured values is possible at the same time. New measurement functions and
ranges not supported by the ALMEMO® devices themselves can be configured and
used via a menu stored in the probe. This makes the new ALMEMO® V7 system
incomparably flexible and future-proof. The communication from sensor to
measuring device is generally carried out via a serial interface. This means that the
D7 sensors can only be connected to new ALMEMO® V7 devices.
4.6 Operation as probe on ALMEMO® V7 measuring
instruments
ALMEMO® D7 sensors supply their final digital measured values of 1 to 10
measuring channels via the serial interface to the ALMEMO® V7 device, where
they are simply stored or output. Function channels can only be programmed and
used by the device. If a measuring channel is not to be displayed, the measuring

range can be deactivated and also reactivated as usual via the ALMEMO® device.
The sensor is supplied via the measuring device.
Extension
The extension cables ZAD7 00-VKxx are used to extend the probes on the device,
where the measured values and the plug programming are transmitted serially
interference-free via RS422 drivers. For galvanic isolation there is an additional
small adapter cable ZAD7 00-GT.
4.7 Measured value correction
For the primary measuring channels, adjustment values or a multi-point adjustment
can be stored in the D7 sensor (ex works or via V7 measuring device with option
KL). Correction values (zero point, slope, base, factor) are already processed in
the probe.

4.8 Sensor menu
In order to maintain the future viability of the new ALMEMO® V7 measuring system
for many years without changing the measuring device, each D7 sensor has an
individual sensor menu that can be called up via each ALMEMO® V7 measuring
device. Thus, it is possible to configure measuring ranges or other specific probe
functions. A V7 measuring device or a PC can serve as the operating device.
4.9 Configuration on the PC via USB adapter cable
The ALMEMO® D7 sensor is directly connected to the PC with the USB coupling
adapter cable ZA1919-AKUV with a baud rate of 115.2 kBd. A microcontroller in
the adapter cable automatically sets the necessary voltage supply as well as baud
rate and device address of the sensor.

The ALMEMO® Control program (from v. 5.14.0.330) is used for configuration via
the sensor menu. In the measuring point list, the 'Sensor menu' can be found
under 'Edit'. Here primarily up to 10 measuring points with the specific D7
measuring ranges of the D7 sensor and further settings can be programmed. The
measuring ranges appear on the interface with new meaningful abbreviations.
Besides the range, a dimension of up to 6 digits and a comment are automatically
programmed and then the channel is locked with 5. Deleting areas is done in the
list by selecting '- - -'.
Function channels are either parameters of the measuring device or are
calculated by the measuring device. They can therefore only be programmed and
used by the device. The following function channels are available:
Batt, Mess, Alrm, Diff, Max, Min, M(t), n(t), M(n), Flow, Time
They cannot be used when connected directly to the PC. The note '!unusable' then
appears in the comment.
