CONTACT CURRENT MEASUREMENT
CCM (Contact Current Meter) measures the contact current flowing through the human body, as the latter makes contact with a conductive object charged by an EM field.
This instrument can verify the compliance with the limits for the exposition to contact current for workers and general public, shown in the ICNIRP guidelines and compliant with the European Parliament directive 2013/35/EU.
The display indication provides the value of the current in mA and the percentage value in relation to the standard.

HAND SETUP
Contact Current Measurement: HAND Mode
The CCM measures the current flowing through the operator (human body impedance).
GROUND PLANE SETUP
Contact Current Measurement: GROUND PLANE mode
The CCM measures the current flowing through the ground plane (human body simulation impedance).

CCM JIG SETUP
This option enables to calibrate the CCM through signal generators in the frequency range 40 Hz – 110 MHz. To verify the limit over 40 mA at 10 MHz, a power amplifier is also required.
MEASURE STORAGE
The CCM allows storing all measures, in an exportable file (CSV extension) including date, time, Workers value, General public value, both LF and HF ranges value and setup used.
