Multi-Point Measurement
You can set the CL-200 up to take measurements from multiple points at once. You do this by
connecting up multiple receptor heads (each with its own adapter). You can connect up to 30
heads. Extra heads and adapters are available as options.
Since all heads must receive a stable power supply, it is essential that you use an (optional)
AC adapter to power the system when taking multi-point measurements.
Required Options
● Adapter Unit for Main Body T-A20
● Additional heads
● Adapter Unit for Receptor Head T-A21, with cable (one T-A21 adapter for each head)
● AC adapter
If cabling is not long enough
If the cable included with the T-A21 adapter is not long enough, you can use 10Base-T net-
work cable (Category 5 straight cable, available at computer supply stores) to make or ex-
tend the connection. When using multiple heads, the maximum allowable total cable length is
50 meters (164 ft).
Setting Up and Taking Measurements
● Note that if the connection cables are in proximity to devices that generate electrical noise,
the noise may adversely affect measurement results and instrument functions. Keep the
cables away from sources of electrical noise when carrying out measurements.
1. Set the power switch to OFF (“
”).
2. Attach the T-A20 to the body.
3. Attach a T-A21 to each receptor head.
