To set up the G-824A to output at a 1000 Hz rate, record the Larmor signal level (to allow
sensor orientation adjustment) and record the Status/ PPS Byte (for synchronization of the
data and to confirm proper magnetometer operation), perform the following procedures:
1.
Power up the magnetometer as described in the previous example
2.
Hold down on the SHIFT key and then the Q key on the computer keyboard to
stop the magnetometer output and go to the configuration menu ASCII prompt
(otherwise go to step 3).
3.
Type ASCII to enter the G-824A's configuration menu. (You may need to type
ASCII twice if you get a “web page” error after typing it the first time.
4.
At the Configuration window Type C. Use the backspace key to edit the Cycle
time to show 0.001 which corresponds to 1 millisecond output (1000 Hz rate).
Hit ENTER, and you will be taken back to the configuration menu.
5.
Hit F to edit the Format menu. You will see a series of questions that need to be
edited as follows:

->
Specify the digital output RS-232 format.
The transmission order of the data source is controlled
by setting the "display position" in the following
table.
The format of the transmitted numbers is controlled by the
format control in the form "###.####". Only the digits you
specify are output, the others are ignored. For example,
15.62 formatted with "#.#" will produce "5.6".
Output format :
(0=ASCII 1=XS3 ):1
Put commas between numbers :
(0=No 1=Yes ):0
Remove unneeded spaces and zeros :
Type F at this prompt to edit the data output
Format
Use backspace and edit this field to show 1 for XS3
