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.
