Starting and connecting the AMV3500

Connecting the sensors
1.1.1
Current sensor
There are two current sensing devices for the AMV3500. A clamp system is mostly used as it is a
convenient and simple way to attach to the welding cable. Secondly an inline sensor, this offers
greater accuracy and repeatability but is less flexible.
1.1.1.1
Clamp Sensor
The current sensor (P332) is clamped around either the torch
or earth return. Practically both sides should measure the
same values.
The clamp will determine a positive and negative flow of
current. The AMV3500 will show only the magnitude of
current on the digital display the direction is shown in the
OSCILLOSCOPE mode.
The clamp meters are iron based and will take an offset as
they become magnetised. Check that the current channel
reads zero, or close to, before monitoring a weld.
Check the clamp has not been mechanically damaged, the
clamp arms should be fully closed and aligned with each
other.
1.1.1.2
Inline sensor
The inline current sensor (P360) fits inline
with the welding cables, either torch or
earth return. The inline sensor uses Dinse
connectors.
