7. How to use Calibration compensation function

Calibration compensation can be made in precise 1/10 step increments in a +/- 1.0 EV. It provides

the ability to match exposure measurements with meters to meters, correct exposure for special

requirements, adjusts for film or digital cameras,etc.

1. Set the measurement mode (incident light, reflected light) for the desired compensation. You

can make calibration compensation independently for both incident, and reflected light. It is not

possible to switch between measurement modes if the setting is not completed.

2. To enter the calibration setting of the meter it must first

be turned off. Press the power button on while holding

down the ISO1 and ISO2 buttons simultaneously. You

can release the power button, however please keep

pressing both ISO1 and ISO2 buttons; the screen will

display CAL 0.0 (for calibration).

3. The calibration setting can be changed by rotating the Jog wheel while pressing and holding

down the ISO 1 and ISO 2 buttons simultaneously. A range of +/- 1.0 EV in 1/10 step increments

is possible for calibration.

NOTE:

• When making calibration compensations, be sure that it satisfies your needs based on

the results of digital camera sensor or film being used.

• While incident and reflected light can be set independently, be aware that both ambient

light and flash exposure are corrected uniformly.

• Compensation effects every mode of the meter. If recalibration has been made for

specific purpose, do not forget to return to original zero settings.

Reference:

• The calibration setting is not displayed on the main screen once it is set.

• You can also set custom setting so that making a plus compensation results in a decreased

exposure (increasing the value of the aperture or shutter speed value) and making a

minus compensation results in and increased exposure (decreasing the value of the

aperture or shutter speed).
