When performing your Electrical Saftey Test(s), what is your setting for max "leakage μA" and " Ω " ?
Thanks

If it's a "K" machine...
According to the Machine Specifications section in the 2008K's operator's manual:

Single Phase AC 120 V +/- 10% 60Hz +/- 3% must be connected and MUST be connected to a GFI.

Resistance from chassis to ground must be <0.2 ohm.

You should also look at Electrical Saftey code UL 60601-1 in the operator's manual as well.

<500uA <.5 Ohm

Which one? .5 or .2 ohm?

Ooops, that should be <300uA. I work in a hospital based Biomed department. All of the equipment in the hospital uses these standards.
<.5 Ohms and <300uA. I believe these are AAMI standards.

We use the same .5ohms for ground resistance and 300uA for leakage, also in a hospital.

EST,

TTech is correct "<300uA and .5 ohm" for hospital based equipment are the AAMI set standards. However, he is not correct about the fresenius 2008K dialysis machine. It must be <.2 ohms. You must follow the strictest; in this scenario, the manufacture is the winner.

TTech,
I also use the manufacture spec of: 0.2

can you tell me the tests that you guys do for leakage?
Normal, closed, machine on/off etc...
Thanks
PS. I thought the max leakage was <100uA

Alex2,

You may be correct on the <100uA for leakage.

When measuring resistance, you verify it is less than 0.2 ohm by measuring with a digital multimeter the resistance between the round pin on the power plug and the redundant ground terminal on the machine.

For Electrical Safety (leakage), you are required to use LOCAL codes, facility procedure and the JCAHO procedures.

You need an Electrical Safety Analyzer to measure leakage. I use a Dale 600 that is several years old. If you have an analyzer I can tell you how I do the tests. If you don't, I can't. Does anyone do all of the ESI testing that's on the B. Braun PM? A little overkill I think. At the Level II they were trying to get us to buy a piece of equipment that would test DC Patient Leakage. Good Luck getting my supervisor to spring for that.

I have a dale analyzer can you tell me how you do the tests.
