Hall effect amp meter telling the truth?

I have a Hall effect current sensor hooked up to my GRT EIS-4000.  I 

have set the parameters in the EIS as stated on the instillation sheet 

for the Hall effect sensor.



When I turn on my 2 GRT Horizon 1 displays, my Val avionics VOR, Garmin 

300XL, transponder (standby) and panel lights I get a reading of about 

.6 on the EIS.



This seems low to me.  How can I verify the current draw.  I don't have 

an amp meter.

Hi Duane

The stuff you mentioned doesn't draw much so it might be OK but I do 

seem to recall having to tweak the settings to get mine to read 

accurately. Best way is a cheap digital meter as I've seen ones that 

will read 10 amps for under $10. You almost  have to have something like 

that in your bag of tools anyway.  For a gross check within 10 or 20% 

how about connecting up something with a known resistance or current 

draw like perhaps a landing light?

Duane,

  

 I was in at our new Harbor Freight store and they had neat little digital  meters on sale for $2.99.  Had a 10 amp scale, too.  I don't need  another meter, but I almost bought a couple anyway.

Duane: 

   

  I have the same setup and it is dead on. 

   

  You reading does sound low but depending on the setting 

of your EIS 

   

  How do you have the S.F. and offset set up? Write me and 

I can help you double check the settings. You also need 

to have sense and decimal setting correct. I assume you 

are trying to read +/- current and have software version 

45 or greater?  

   

  Some settings (+/- 50 or 100 amps) are designed for no 

decimal, meaning resolution is 1 amp and there is no 

decimal 1/10th in the display. I am curious to know 

why you have 0.6 displayed? May be it is 6 amps?

   

  The sensor is somewhere between 0.5% to 2%. which 

should not cause that much difference. 

   

  You may need to adjust the Aux offset. You change it 

2 at a time and must remain a odd  number. I assume 

it reads zero other wise with all devices off. (except the 

master relay will draw about 0.60 amps alone)

   

  I guess it is a setting issue and not a sensor issue.

   

  I am wondering why you choose to route the battery 

cable through the sensor and not the alternator b-lead? 

   

   

   

  Cheers George

Yes I bought one and  tested it against a calibrated meter from work...The current meter was  remarkably accurate!
