Page 6: General Information
USER MANUAL 1. General information 1.1. Introduction CCM was designed to measure in a fast and accurate way the contact current that may be generated when touching electrical/electronic equipment inside a radio frequency field. 1.2. Description CCM (Figure 1-1. CCM) is a portable measuring device with two measurement modes. -

Page 9: Principle Of Operation
Figure 2-1. CCM block diagram 2.2. Measurements The CCM digital nature allows it to measure contact currents through the true RMS (Root Mean Square) value for all analog signals from 40Hz. The RMS value of a waveform signal is equal to a DC current which provides the same power to the load. -

Page 22: Data & Time
USER MANUAL 4.7.5. Data & Time The fifth menu item allows you to change the date and time of the device (Figure 4-15). It is important that this information is correct, because the results of the measurements in the downloaded data (csv file generated by the device) are associated with the day and time of the measurements. -

Page 26: Data Download
The data downloading operation has been designed to improve the speed and simplicity of use. The data generated by the CCM are stored in csv (comma separated value), which is a text file with value separators. This allows the user to read, edit and process the downloaded data via various software including MS Excel. -

Page 28: Jig - General Information
Figure 6-1. CCM and JIG 6.2. Description The JIG is built on an iron base, with a connector to be plugged to the CCM's Jig room, an iron locking stirrup designed for the HAND plate, and adaptive connectors designed for the contact current meter. This guarantees a stable support during the test procedure. -

Figure 7-3. Set Up the JIG The next step is to lock down the CCM with the special JIG lock using the knobs, so that the HAND plate will be connected to the lock sma connector (the result is shown in Figure 7-4). -
Page 32: Hand" Test
USER MANUAL As already described on the CCM manual, the GROUND PLANE measure has to be done before the HAND measure. To properly connect the device plane connector to the generator we will use our N-sma cable and the R45 resistance as in Figure 7-5. -
