To set the time delay between pulses use the count up (RANGE) and count down buttons (MODE)
buttons to enter the time in seconds. Press the SELECT button after the time has been entered to save the
setting. The following time delays are recommended:
AC2500, AC25HD 60 seconds
AC2501, AC25HD, AC2504 60 seconds
AC5000, AC50HD 90 seconds
AC5001, AC50UV, AC5004 90 seconds
360401 with interface module 105 seconds
380401, 380402, 384UV5 with interface module 180 seconds
360801 with interface module
125 seconds
380801, 380802, 388UV5 with interface module 200 seconds
H. The "At" (attenuation) annunciator now appears in the display. If no attenuator is being used in
conjunction with the calorimeter, the attenuation factor in the display must be set at 1.000 since this
value is a display multiplier. Attenuation multipliers from .0001 to 9999 can be entered into the
displayed value.
The attenuation factors of optics can be entered into the S310 so the displayed value will automatically
compensate for the amount of attenuation. For example, assume a beam splitter is being used that
transmits 75% and reflects 25% of the beam. If the S310 is set up to measure the reflected beam the
attenuation could be set up as follows:
• An attenuation factor of 1 would display the value of the reflected beam.
• An attenuation factor of 3 would display the value of the transmitted beam.
• An attenuation factor of 4 would display the value of the source.
Use the count up (RANGE), count down (MODE) buttons to change the attenuation factor. Press the
SELECT button to enter the attenuation factor to memory.
I. If The S310 has the optional IEEE488 interface, the REMOTE annunciator will appear along with the
digital interface previously selected; r232 (RS232) or IEEE (IEEE488). Press the SETUP button to
toggle the interface between r232 (RS232) and IEEE (IEEE488). Press the SELECT button when the
desired interface appears in the display.
J. If the optional IEEE488 interface was not installed, the "br" (baud rate) annunciator for setting up the
RS232 interface appears in the display along with the baud rate previously selected. To change the
baud rate press SETUP button until the desired baud rate appears in the display. One of the following
baud rates can be selected: 300, 1200, 2400, 9600, and 19,200. When the preferred baud rate appears in
the display press the SELECT button.
K. The "PA" (parity) annunciator now appears in the display. Press the SETUP button to select none, even,
or odd parity. Press the SELECT button to enter the parity of choice to memory
L. The "HS" (handshake) annunciator now appears in the display. Press the SETUP button until your
choice of none (nOnE), on/off (onoF), or clear to send (CtS) appears in the display. Press the SELECT
button when your choice is displayed to enter the handshake to memory.
M. If IEEE488 has been selected, the "bA" (bus address) annunciator appears with the default bus address.
Bus addresses from 0 to 30 may be selected by pressing the count up (RANGE) count down (MODE)
buttons followed by the SELECT button. Once the remote interface has been setup, the group
annunciator will appear. Press the SELECT button or simply wait a few seconds and the group will
automatically be selected for operation.
