ZERO CALIBRATION
Zero calibration is performed to determine the output of the measuring probe when no light reaches the sensor and to set this as the zero
point to which all other measurements are referenced. Zero calibration must be performed after the POWER switch has been set ON
brfore taking any measurements.
To perform zero calibration :
* Before performing zero calibration, check that the measuring probe has been connected to probe
connector P1.
1. Check that the POWER switch is set to ON.
2. Set the measuring/viewing selector to the
(viewing) position. (An image can be seen in the
viewfinder, but no light will reach the sensor.)
3. Press 0-CAL.
* If zero calibration is being performed immediately
after the POWER switch has been set to ON, press
0-CAL after "PUSH 0-CAL KEY" appears in the
liquid crystal display.
