The 90M10-AG and 90M10 are Non-Invasive Clamp on Sensors.
The mAs sensor connects to models Accu-Gold / Rapid-Gold / Accu-Pro / Accu-kV and couples to the X-ray generator by clamping to the X-ray anode HV cable (clamps up to 23mm diameter).
The Accu-Pro and Accu-kV require a kV sensor in-beam as a trigger source.
To measure Anode current, clamp on the anode cable with the arrow on the clamp pointing towards the X-ray tube. For best results, do not move clamp before and during a measurement or place next to the X-ray tube.
