The current clamp has two calibration settings, set by a slider switch on the handle of the probe.

1. 1 mV/10 mA (100 mV = 1 A)
   — use this for testing currents up to 20A.
2. 1 mV/100 mA (10 mV = 1 A)
   — use this for testing current up to 60A.

In use there is no need to break into the circuit or disturb the isolation as the opening jaws simply clamp around the current carrying conductor. No electrical contact is required.

The PP218 current clamp is supplied with 4mm (banana) plug type connectors so can not be plugged directly into the PicoScope. To connect to the PicoScope we recommend the use of the TA000 BNC to 4mm test lead, alternatively the MI078 BNC to 4mm plug adaptor can also be used.

The PP264 current clamp features a BNC connector and can be plugged directly into the PicoScope.
