Adjusting Driver Current with a Multimeter
To adjust the driver output to a specific value, you must first wire a multimeter into your LED
string and second, you must ensure the DIM+ and DIM- wires are connected to a dimmer. The dimmer
should be set to full brightness.
The multimeter should be wired into your LED string exactly the same as an LED, + to -, in fact, if
you just pretend it is an LED, you will have no problem measuring current. If you wire the multimeter in
backwards, it will still work, but your measurements will be negative instead of positive.
To set your multimeter up for measuring current, move the RED probe plug to the 10A socket
and rotate the knob to the 10A position. Multimeters can differ in operation. Please consult your
multimeter manual for model specific operating instructions.
As in the photo below on the right, have a friend firmly hold the probes in a gap in the LED
string. We had to remove a wire in an existing setup for this example. If either probe loses contact with
a solder pad on either LED, do NOT re-touch it to the LED until power has been removed from the driver
for a few minutes, and then start over from the beginning.
