MODEL 370 REV: D Page 7 of 26
Linear: For normal average measurements.
Log Ratio: For logarithmic average ratio measurements of the
signal to the previous measurement, which is saved when using this
function. To change the reference value, change mode to linear, start
measurement, adjust signal and change the mode back to log ratio.
Ratio: Performs linear ratio of the signal to the previous
measurement, which is automatically stored when using this
function. To change the reference value, change mode to linear, start
measurement, adjust signal and change the mode back to log ratio.
Responsivity/User Entered Responsivity: Displays the set
responsivity. Pushing the start/stop key moves cursor from left to
right. Pushing up/down key changes values at cursor (sign, value and
measurement units). When the last character is set, pushing start/stop
key will display measurement units which can then be changed.
Analog/Digital: Changes the digital reading to analog reading or
analog reading to digital reading. When in analog reading, the scale
factor may be changed by pushing the up/down keys. Display returns
to the normal scale when start/stop is pushed twice.
Calibration Select: Pushing calibration select displays calibration.
Typical Display: 268R S/N 17790
The message, usually containing the detector model number, serial
number. Other Calibrations are obtained by pressing the up/down
key.
Wavelength Select: The calibration status is displayed.
Calibrations at other wavelengths may be obtained by using the
up/down keys. The keys will scroll through the available
wavelengths with auto repeat if held down.
Zero: Saves previous readings for subtraction from following
readings. A cursor will appear on the right side of the display. To
implement the zero function, push the zero switch again, a “z” will
appear on the right side of the display. The cursor or “z” will not be
displayed if the start/stop key is pressed following the zero
procedure. To change back to a non-zeroed measurement, press the
zero key so that the cursor is obtained on the right side of the display.
If the measurement function is log ratio or ratio, pressing zero in half
mode will display the value of the reference signal.
Start/Stop: Begins or halts the measurement cycle. Pushing start
clears the display and begins measurement.
