3. Group Settings for Vector  Pyroelectric Detectors and Vector HR Pyroelectric
Detectors:
Note: The factory default Group for Vector Pyroelectric Detectors is Group #2.
Note: The factory default Group for Vector HR Pyroelectric Detectors is Group #3.
Note: Pressing the CANCEL button at any time during this process will terminate this process
with no changes made.
Note: Holding down the SELECT button for 3 seconds at any time during this process will save
any changes made up to that point and return the S310 to its operational state for the
Group selected.
Note: If you want to use the transfer calibration function, you must select the watts mode prior to
entering the Group configuration program.
To review, change, or setup a Group Setting for Vector Pyroelectric or Vector HR Pyroelectric detectors,
proceed as follows:
A. Press the SETUP button. The Group Setting last used will appear in the display.
B. To move to the next Group, press SETUP button again.
C. To select a Group, press the SELECT button when the Group you desire appears in the display (failure
to press the SELECT button within 3 seconds will activate the Group shown in the display and return the
S310 to its operational state).
D. Press the SETUP button until the "PYro" annunciator appears. Immediately press the SELECT button
to select the pyroelectric detector configuration program.
E. Either the "V/J" annunciator or the "V/mJ" annunciator and a detector sensitivity number will appear in
the display. V/J is used for standard pyroelectric detectors. V/mJ is used only for HR pyroelectric
detectors. Press the SETUP button to toggle between the V/J and V/mJ entries. The output sensitivity of
the pyroelectric detector in V/J or V/mJ is listed on the serial tag of your detector. Use the count up
(RANGE) and count down (MODE) buttons to enter the V/J or V/mJ value. Press the SELECT button
to enter the value to memory. Do not push the SELECT button before entering the sensitivity number as
this takes you to the next setup step without the proper sensitivity number.
F. The "SP" (speed) annunciator now appears in the display. Press the SETUP button to toggle between bL
(black or HD coated detectors) or hF (high frequency) detector. If the detector Model No. includes the
letters “HF”, press the SELECT button when the hF annunciator appears in the display. If the detector’s
surface is black (does not have the letters “HF” in the Model No.) press the SELECT button when the
"bL" annunciator appears in the display.
G. The "AUTO, SET CAL" annunciators now appear in the display (only if watts mode was selected prior
to group configuration). This is the Transfer Calibration function. The Transfer Calibration function is
designed to transfer the calibration from a NIST certified calorimeter to a Vector pyroelectric detector.
This function allows you to adjust the output sensitivity of your Vector pyroelectric detector in
combination with your S310 meter (in the average power mode) in order to match the average power
reading of a NIST certified system. Typically a 50/50 beam splitter is used with the Vector pyroelectric
detector to be calibrated in one beam path and the NIST certified calorimeter in the other beam path.
You are to adjust the output sensitivity of the pyroelectric detector while it is operating by using the
count up (RANGE), count down (MODE) buttons, which change the V/J or V/mJ settings, to make the
displayed value of the S310 power reading the same as the NIST standard. Press the SELECT button
when the readings match.
