Chapter 7 Calibration 57
g. Input the second actual (measured) photodiode current as in
Step e.
h. Once the actual photodiode current value is entered via the
second
LAS:MDI
command, the 5600 leaves the current
calibration mode.
If, at any time prior to the second
LAS:MDI,
a command other
than
LAS:MDI
or
LAS:CAL:MDI?
is sent to the 5600, the
5600 will cancel the calibration mode and then process the
command(s).
The *
OPC?
query may be used to determine when the
calibration is completed.
The operation complete flag (bit 0 of the Standard Event Status
Register) may be used to trigger an interrupt. This type of
interrupt is enabled by setting bit 0 of the Service Request
Enable register and using the
*OPC
command.
7.2.6 Local Operation Laser Voltage Measurement Calibration
a. With the output off, connect a calibrated voltmeter, in parallel
with the shunt to the laser output terminals.
b. With the unit in Io mode, press the
LDD ON
key to turn the
laser output on, if it is not on already. If a laser on delay has
been set, wait that amount of time to allow the laser output to
engage.
c. Start the calibration procedure by first pressing the
MENU
button, then right arrow until the
Calibration
menu is reached,
then presses the down arrow until the
Im Calibration
function
is selected, then the right arrow key to execute the Im calibration
function.
d. The current output will be set at ½ full scale and allowed to
settle. Once settled, enter the actual voltage measurement from
the ammeter display, then select the
Next
soft button and press
the right arrow.
