Re: [PSES] Handheld or portable voltmeter/ammeter with built-in and adjustable limit function with audible alarm

[Ed Price]

Alfred’s comment reminds me that I just bought a fairly decent DMM, a Uni Trend 
UT-61E. This is an auto-ranging 5 digit, 60k count DMM with 0.1% accuracy on 
DCV, and it cost only about $65. One important feature is that this DMM 
includes an optically isolated USB interface, plus a free data acquisition 
suite for my laptop. With just a bit of effort, you could have your laptop 
monitor the data stream and provide alerts as desired (the software is already 
set up to create Excel files and create extensive data graphs).

If none of these meet your needs, you can always find any number of those with 
a programming API and write a program to do whatever you want. Many support USB 
interface. You can get a cheap windows tablet as the buzzer and attach to the 
meter through USB.

For an EMI test, I need to monitor direct current and set a limit above which I 
get an audible alarm.  I don’t want to constantly have to watch an 
ammeter/voltmeter while also operating the susceptibility equipment. I also 
don’t want to have to connect a DVM to a PC; I want the limit setting function 
to be self-contained.  Seems as if there ought to be such a device, but I can’t 
find it. Doesn’t have to be an ammeter per se; if it can measure dc millivolts, 
I can use a current shunt.

Blue Sea sells some stuff intended for boat owners. Not sure if any of it is 
adaptable for your use. They offer audible and visual alarms.

Re: [PSES] Handheld or portable voltmeter/ammeter with built-in and adjustable limit function with audible alarm

[Ed Price]

Ken:

 

I had a hand-held DMM, back around 1992, which did something close to that.
IIRC, it was made by Beckman (which later sold that division to Fluke). It
had the ability to create a tone whose frequency was proportional to
whatever function and range you had selected. I found it very helpful in
tracking down cable shield problems because you could set it for a
resistance measurement and then walk around some big system shaking cables
and structure pieces while listening to the tone.  Setting it for DCV and
connecting it to the video output on an EMC receiver would give me an
audible indication of RF signal strength. Unfortunately, it was only
proportional and you couldn't set an alarm or trip point.  Seems like in
these days of microprocessors everywhere, somebody ought to have a DMM
option that has high/low limit set-points and even speaks to you.

 

If any DMM you have has an output of some sort (like the ancient Simpsons
VOM's had), you could build a simple oscillator and comparator into a small
box and use that connected to that "monitor" output of your DMM.

Dear John,
 
Yes, you are quite right this type of product is very challenging to meet 
relevant standards.  However, I notice some well designed and approved products 
appear on the market.  Thus we need to look into it if any product has achieved 
to a minimum safe level and encouraging more better design entering into 
market.  Eventually, it is benefit to the users.  In the past, most of products 
were poor in design and no products passed in their compliance test.
 
You point out the applicable standards for mains connector part.  Does this 
part need to comply with the plug and socket law which requires certification 
mark, QMS audit and production audit by appointed bodies or just subject to a 
type examination against the standards by an accredited laboratory?  Are 
similar requirements applied in other countries, such as Germany, US, Japan, 
etc., which the product is intended to be used?
 
Thanks and regards,
 
Scott

[PSES] Handheld or portable voltmeter/ammeter with built-in and adjustable limit function with audible alarm

[Ken Javor]

For an EMI test, I need to monitor direct current and set a limit above
which I get an audible alarm.  I don¹t want to constantly have to watch an
ammeter/voltmeter while also operating the susceptibility equipment. I also
don¹t want to have to connect a DVM to a PC; I want the limit setting
function to be self-contained.  Seems as if there ought to be such a device,
but I can¹t find it. Doesn¹t have to be an ammeter per se; if it can measure
dc millivolts, I can use a current shunt.

Thank you,

Ken Javor
