General information
Intelligent current clamp meter ISMZ I –User Manual 5
General information
Please read this document thoroughly from start to finish before you begin using the device for the first
time.
Purpose of use
The Intelligent current clamp meter EMCheck® 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
The Intelligent current clamp meter EMCheck® 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
Switching on/off
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). To switch off the ISMZ, the Power button
(1) has to be pressed for a longer time.
Standby mode
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.
Menu control
Press the Mode button (2) to leaf through the menu of the clamp to access the settings and functions.
The following menu pages are available:
CURRENT - Effective value measurement (main menu)
CURRENT COURSE - Course of the current over time
SPECTRUM - Display of frequency specter (0…20 kHz)
TEACH… - Automatic teaching of trigger thresholds
REC. CONFIG - Configure recordings and trigger
SETTINGS - Basic settings of the measuring clamp
STATUS - Memory and battery, status of the recordings
You can confirm entries by pressing the Enter button (8).
Use the arrow buttons (6), (7), (9) and (10) to scroll through the menu and also to change input values and
zoom stages.
With pressing the Rec button (4) the time of recording or time of observation (trigger mode) can be started
or stopped.
Switch the display light on and off by pressing the button Display light (3).

Carrying out recordings
Intelligent current clamp meter ISMZ I –User Manual 12
Carrying out recordings
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 permanentor triggered recording byconfiguring
the recording options.
Configure recordings
Switch into the RECORD 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
PERMANENT 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 by button REC (4) and selection of a
time with arrow buttons (7), (9), and the button Enter (8). The
following values are possible:
1 minute
3 minutes
5 minutes
10 minutes
15 minutes
30 minutes
1 hour
4 hours
8 hours
15 hours
1 day
2 days
3 days
∞ (permanent recording)
The recording is stopped by button 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
software EMCheck®View.

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 RECORD MENU, the set trigger thresholds for the current
level and the current inclination appear in the display.
6.1.2.1 Specifying the trigger thresholds manually
Use the arrow buttons (7) or (9) to switch to RECORD MODE
TRIG.
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 monitoring is started and stopped as described in 6.1.1
Permanent recording.
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 TRAINING… menu with the Mode button (2).
Select ADD THRESHOLD 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 PERIOD with the arrow buttons (6) and (10).
If the function MANUAL is used, the training time can be started
with selecting start with arrow buttons (6) und (10) and confirming
this with button (8).
From now the ISMZ will measure the LEVEL and SLOPE of the
current. The measured values will be shown in the display.
If the TRAINING time should be stopped, the button (8) has to be
pressed.
After stopping the TRAINING time the window RECORD MENU
will be shown and the monitoring can be started as described in
6.1.1 Permanent recording.

Carrying out recordings

Select PERIOD with the arrow buttons (6) and (10).
Switch from MANUAL to a time (5 min, 10 min, 15 min, 20 min, 25
min or 30 min) to observe the current and set the trigger threshold
by using the arrow buttons (7) and (9).
After choosing a PERIOD to add the trigger threshold the
MON.PERIOD (time of monitoring) should be chosen with the
arrow buttons (7) and (10), as described in 6.1.1 Permanent
recording.
Select START with the arrow buttons (6) and (10) and confirm to
start the measurement with button (8).
The clamp will now learn the trigger thresholds and start
monitoring afterwards.

Copying recordings to the PC
There are two methods for copying the recordings from the ISMZ I onto your PC.
1) Remove the micro SD card from the clamp and take it from the adapter board. You can now read
the micro SD card using a removable medium reader with an adapter to USB or standard SD.
2) Connect the ISMZ I with the integrated memory card via USB to your PC. A USB cable is included
in the scope of supply.
Open the EMCheck®View software.
Select "Adjust clamp" (on top, on the right side)
Follow the instructions of the software –it´s recommended to use “Wizard”
Once the connection has been established, you can make settings on the clamp and use it as
