MAT 6V/15V/25V/36V/ 022300

d.

The MAT previously set up now starts to measure and send the proper time delay
needed for the measurement.

e.

The  Power  Module  Controller  will send  the   time  delay  value back  to  the  Host  Com-
puter when it has been  properly  Talk  Addressed  (see  specific  IEEE  488  interface
requirements):
00(cr)(lf)

1.

The Host Computer then sends:

FTH  CURR(cr)(lf)

a.

The MAT then sends the measured current in scientific notation to the Power Module
Controller (for example 9.9998 amps) which

b.

The Power Module Controller  in turn sends

 9.9998E0(cr)(lf)

3.

Check that the front panel meter reading and the computer are identical within their mea-
surement tolerance. The meter selection switch must be set to "Current" for a reading.

2.8.3

EXAMPLE 3: TO RESET THE POWER MODULE

4.

 To reset the Power Module at address 3 the Host Computer sends:

RST  DCS  :CH3(cr)(lf)

5.

To verify the RST command was implemented, the Host Computer sends:

STA(cr)(lf)

The Power Module Controller sends back (if no errors occur):

(sp)(cr)(lf)

6.

 This concludes the preliminary check-out  of the MAT Power Module.
