What current probes are compatible with the CT4 current transformer?

The CT4 can be used to extend the measurement capability of the P6021/A, A6302, A6312, TCP202/A,TCP0020 and TCP0030/A.

The CT4 can also be used with the TCP 312/A and TCP305/A along with the TCPA300 amplifier.  

On some instruments, you may need to set the external attenuation factor to 20X or 1000X, depending on the receptacle used on the CT4. This is done in the VERTICAL menu.

TheTCP0030/A is also compatible with the CT4 and the DPO4000 and DPO7000 series oscilloscopes.  There is one limitation when the TCP0030/A and CT4 is used with the DPO4000 series. External attenuation factors cannot be entered.  You will need to manually multiply the readings by either 20X or 1000X.

In all cases, Amp/seconds ratings of the probes are not to be exceeded.
