General information
Intelligent current clamp meter ISMZ I – User Manual 5
General information 1
Please read this document thoroughly from start to finish before you begin using the device for the first
time.
Purpose of use 1.1
The Intelligent current clamp meter E M Check® ISMZ I is a mobile measuring device for conductor-
bound interference currents. In standalone mode, the measuring clamp independently measures current
values and continuously records the current course. Its integrated intelligence allows the user to make
preliminary inspections and thus first estimations on the electromagnetic compatibility (EMC) of industrial
systems.
The following measurements can be carried out:
Current effective value (RMS)
Current course
Spectrum
To record the current values, an SD card is necessary, which is included in the scope of supply. All
recorded data can be evaluated using a corresponding PC software.
Technical data 1.2
The Intelligent current clamp meter E M Check® ISMZ I is suitable for recording conductor-bound
electrical currents in the following ranges.
Measuring range: 10 mA to 30 A
Frequency range: Sampling frequency 10 kHz: 40 Hz to 5 KHz
Sampling frequency 20 kHz: 40 Hz to 10 KHz
Sampling frequency 40 kHz: 40 Hz to 20 KHz
Battery life: 336 h (14 days)
Changing the sampling frequency also changes the measurable frequency range. The sampling
frequency should always feature at least the double value of the frequency to be measured.
The maximum monitoring time of 14 days is available when a sampling frequency of 10 kHz has been
set. If the sampling frequency is increased, the monitoring time / battery life is reduced due to the
increased current consumption.
Six LR6 (AA) batteries are needed to operate the ISMZ I. Please do not use any rechargeable
batteries.

Operation 3
Switching on/off 3.1
Pressing the red Power button (1) switches the ISMZ I on. When the clamp is switched on, it can be set
into standby mode by briefly pressing the red Power button (1). Pressing it longer switches the ISMZ I off.
Standby mode 3.2
The standby mode is a power-saving function. All measurements remain active and are not lost. You can
also specify in the settings how long the period of inactivity should be before the clamp automatically
switches into standby mode. The display is deactivated in standby mode. Standby mode is indicated by
brief flashing of the standby LED.

Carrying out recordings
Intelligent current clamp meter ISMZ I – User Manual 12
Carrying out recordings 6
The ISMZ I is capable of recording current values continuously and to save these on the SD card. The
recordings are either saved without interruption during a permanent recording or only during specified
trigger events. Before starting a recording, choose between permanent or triggered recording by
configuring the recording options.
Configure recordings 6.1
Switch into the RECORD CONFIG menu with the Mode button (2).
Use the arrow buttons (6) and (10) to select RECORDING.
Use the arrow buttons (7) and (9) to choose between
PERMANETNT and TRIGGERED.
PERMANENT – permanent recording
TRIGGERED – triggered recording
6.1.1 Permanent recording
All current values are recorded without interruption during a permanent recording and saved on the SD
card. No trigger thresholds are therefore necessary.
The recording is started and stopped by REC (4).
Once the recording is being actively conducted, the abbreviation REC appears in the display. The ISMZ I
saves all recordings on a micro SD card in "*.EMC" format. The directories are saved temporally in the
format YYYY-MM-DD and the files in the format hh:mm:ss. Recordings can be evaluated with the
included E
M -Check View software.
6.1.2 Triggered recording
During a triggered recording, current values are only registered if the set trigger thresholds are exceeded.
You can specify the trigger threshold automatically by a teach-in process or configure them manually.
Once you have chosen the triggered recording in the REC. CONFIG menu, the set trigger thresholds for
the current level and the current inclination appear in the display.

Carrying out recordings
Intelligent current clamp meter ISMZ I – User Manual 13
6.1.2.1 Specifying the trigger thresholds manually
Select the LEVEL with the arrow buttons (6) and (10).
After pressing Enter (8) on LEVEL, the current value can be set by
the arrow buttons (6), (7), (9) and (10) that should actuate the
trigger if exceeded. Confirm by pressing Enter (8).
Select the SLOPE with the arrow buttons (6) and (10).
After pressing Enter (8) on SLOPE, the current change in A/ms
can be set by the arrow buttons (6), (7), (9) and (10) that should
actuate the trigger if exceeded. Confirm by pressing Enter (8).
The recording is started and stopped by REC (4).
6.1.2.2 Teaching of trigger thresholds
When trigger threshold are taught, the ISMZ I registers all current levels and current changes during the
process. Before the teaching process, specify by which amount the trigger thresholds should be higher
than the registered values (e.g. by 20 % higher). Furthermore you set a specific teaching time or start and
stop the teaching manually.
Switch into the LEARNING menu with the Mode button (2).
Select THRESHHOLD ADD with the arrow buttons (6) and (10).
Use the arrow buttons (7) and (9) to set by how much the
operationally prevailing current needs to be exceeded so that a
start trigger is actuated (e.g. 20 %). Values between 0 % and 95 %
are possible.
Select TIME with the arrow buttons (6) and (10).
Use the arrow buttons (7) and (9) to set how long the ISMZ I
"observes" the operational currents to generate a trigger threshold
from that.
(Example: Set the time in a production line so that ten complete
production cycles are recorded.) The following values are
possible:
5 minutes
10 minutes
15 minutes
20 minutes
25 minutes
30 minutes
As an alternative, the teaching time can be set to MANUAL. The
teaching mode runs until it is stopped manually.
Select START with the arrow buttons (6) and (10).
The maximum current value as well as the highest incline are
displayed in the display during the teaching.
After completing the teaching, the trigger thresholds are adopted
for the REC. CONFIG menu and the recording starts
automatically.
For a manual teaching time, the recording can be started and
stopped by REC (4).
