Hey guys,
I got a Coherent Model 200 Analog LPM and I'm trying to see 1) if it works and 2) if I'm reading it correctly or if it isn't reading my 405 and 450 correctly.
This is the meter Off and in the Battery Test position:
This next one is with the meter set to .3 It's reading the only laser I have that's been tested by another LPF member. PLE-Pro 473 that Wannaburn measured at around 100mW
I'm assuming at this point that the big numbers on top correlate to 100'S of mW
This next one is of a 5V fasttech module. Pman has measured these at around the 100-140 mark being cheap 532 modules they could be all over the place.
Again it seems to be on par with what's expected
I measured my PL520 at about 90mW which seems low for the 300mA it is set at. But maybe I just got a crappy diode... I have pictures but decided not to include them for brevity as you all get the idea.
Then there's the PL450 set at 200mA...
440mW???? :thinking: Somethings wrong here
Then there's my PHR805:
Nearly 300mW???? Again, even for a freak diode there isn't anyway these readings are correct... Right?
Any insight you guys can give would be a HUGE help. I don't have a clue as to how to actually read this, I just took my best S.W.A.G. at it.
Thanks,
Javalin
