North Atlantic 2250 PAV

HI All,

I'm using the NA2250 to obtain a VRMS measurement of 300V 400Hz. I'm able to tell the unit what settings I want but, I'm unable to obtain the measured value using [I] or [I$] (currently using the MEMI command to input the display data).

I’m using METCAL V7.2  and failed with this attempt (and a few different combinations).

  IEEE         [D2000]
 IEEE         "INX VRMS"[13][10]
  IEEE         [D2000]
  IEEE         "FTH VRMS"[13][10]
  IEEE        [I]
  MEMCX   300   V             2U          400H

If anyone could offer working data retrieval commands? I would be very grateful.

Mark

You need to use INX MAIN to read the main display or INX FREQ to read the frequency display.

Try this:

 

IEEE     FNC RMSV[X0D0A]                                ;Configure Total mode

IEEE     SRX VOLT 500[X0D0A]                          ;Configure for 500 volt range

IEEE     INX MAIN[X0D0A][D500][I]                     ;Initiate read of main display

 

This code works for me.  Hope it helps.

Hi Mike, thanks for your reply.
I’m unable to use the Hex code (illegal command).

The 2250 will only respond when I use " "

This attempt hangs at step 1.009 (or 1.008 if [I] is on same code line)
# set up 2250
  1.001  IEEE         "FNC RMSV"[13][10]
  1.002  IEEE         "SRX VOLT 500"[13][10]
  1.003  IEEE         "SET RREF OFF"[13][10]
  1.004  IEEE         "SET VARI OFF"[13][10]
  1.005  IEEE         "SET RTIO OFF"[13][10]
  1.006  IEEE         "SET ACAL ON"[13][10]

Apply 300V 400Hz, wait for lock then advance

# get display value
  1.007  IEEE         [D1000]
  1.008  IEEE         "INX MAIN"[13][10]
  1.009  IEEE         [D500][I]
  1.010  MEMCX  500   300.0V         2U          400H

Any suggestions welcome

Im not using the quotation marks in my code. My MET/CAL version is 8.1.7.

Try this:

IEEE   [TERM CR]

to specify the terminating character from the device.
