Adjust the zero level of the recorder so that the analog output
voltage from the instrument equals to the zero level of the
recorder.
7
Remove the cap (or block).
An analog signal (i.e. voltage) proportional to the measured
illuminance will be output, and the measured illuminance
will be recorded continuously to the recorder.
z
A voltage corresponding to the displayed significant digits (0 to 3,000 mV) will be output, irrespective of
the currently selected range. The range corresponding to the output voltage is displayed in the display
section.
z
In CCF mode, a signal corresponding to the measured value will be output, irrespective of the CCF.
z
The recorder to be connected to the analog output terminal must have an input impedance of 1 MΩ or
higher. Since the output impedance of this instrument is 10 kΩ, the indication error will be 1% or less if
the input impedance of the recorder is 1 MΩ or higher.
z
The measured illuminance is always output from the analog output terminal, irrespective of what is
displayed. Thus, it is possible to display the illuminance difference/ratio or integrated illuminance or hold
the displayed value even if recording is in progress.
z
To observe the waveform of a flicker light with an oscilloscope, select the range that does not cause
the peak value of the flicker light to exceed 3,000 mV.
