Sensors
(MultiSpectral models only)
Choices include: UV only, IR only, or UV + IR. This parameter is used to manually select which
sensor(s) are used in a particular file.
IR Band
The display is divided into two halves. The left side displays the selected IR flicker frequency bandpass
(i23). The right side displays the Signal Strength (/999) attributed to the IR sensor.
For example a reading of i109/400, would indicate an IR band of 109 Hz with a corresponding Signal
Strength of 400 is running. The band can range from 23 Hz to 179 Hz, while the Signal Strength can
range from 0-999.
Pressing the UP or DOWN keys changes the frequency band displayed and immediately stores the value
(pressing the PROGRAM key is not required). The user will immediately see the effect on the Signal
Strength.
IR Gain
The display is divided into two halves. The left side displays the selected IR Gain (iG31). The right side
displays the Signal Strength attributed to the IR sensor.
For example a reading of iG26/600, would indicate an IR gain of 26 with a corresponding Signal Strength
of 600. The IR sensor Gain is selectable from 1(lowest) to 31 (highest), while the Signal Strength number
can range from 0 to 999.
Pressing the UP or DOWN keys changes the gain displayed and immediately stores the value (pressing
the PROGRAM key is not required). The user will immediately see the effect on the Signal Strength.
Each increment of the gain will increase the Signal Strength number for the IR sensor by 50% (e.g.
changing IR sensor gain from 26 to 27 would increase the IR Signal Strength from 600 to 900).
Each decrement of gain will decrease the Signal Strength number for the IR sensor by 33% (e.g. changing
IR sensor gain from 27 to 26 would decrease the Signal Strength from 900 to 600).
IR Range
There are two selectable internal “ranges” for the IR sensor Gain, “High” and “Low”. If a flashing IR
number is observed when “Aiming” the detector, then the signal is over range and the IR Range should be
set to “Low”. If, when “Aiming” the detector, an IR number of less than 10 is observed, then the IR
Range should be set to “High”.
UV Band
The display is divided into two halves. The left side displays the selected UV flicker frequency bandpass
(u23). The right side displays the Signal Strength (/999) attributed to the UV sensor.
For example a reading of u109/400, would indicate an UV band of 109 Hz with a corresponding Signal
Strength of 400. The band can range from 23 Hz to 179 Hz, while the Signal Strength can range from 0-
999.
Pressing the UP or DOWN keys changes the frequency band displayed and immediately stores the value
(pressing the PROGRAM key is not required). The user will immediately see the effect on the Signal
Strength.
