It's an Altek Model 434 milliamp calibrator.
I have no idea what that would be used for.


D from BC
it's used to calibrate devices that operate with 4..20 ma of
current. Things like mechanical actuators for air, water, steam or
just simply moving things or, in signal devices like current loop for
multiple forms of long distant communications over wire..
It's simply a programmable current source that you can connect
directly to the device to make adjustments to the device to make sure it
spands correctly in the standard 4..20 ma range... When done, you simply
connect back up to the device the driving electronics which will control
it via it's output of 4..20 ma..
This calibrator normally is battery operated so that it's portable.
A must tool for those that are in HVAC or any form of industrial
controls where it may be hard to get at when setting up and calibrating
the devices..

Well..if this calibrator is selling for ~900.00,...that's as wacky as
the wrong picture or wrong title.

It's like $2 in parts to make a precision current source in the 4 to
20mA range..

This is the sort of thing that happens when you name your web site
photos something like 434.jpg and then upload all of them to the same
subdirectory.

Why, to "calibrate" miss Millie Amp some fine evening...

Does it come with a probe, or must one supply his own?

Well, if you do not know the answer to that, go back to Biology 101...
