Rite Life 393, 394 manual Applying Power

Applying Power

The sensitometer is shipped from the factory with the battery installed and power switch in the “Off” (left) position—slide switch to the “On” (right) position. The battery switch for the 393 is located on the front of the instrument. The battery switch for the 394 is located on the bottom of the instrument.

Because there is no drain on the battery during non-use times, the power switch can remain in the “On” position. The only time that the power switch must be turned “Off” is when the instrument is transported or the battery replaced.

Your sensitometer is designed to operate from a “9 Volt” alkaline battery for approximately one year. When the battery is low, the circuit will not allow any exposures to occur. Should your unit become inoperative, replace the battery first, refer to Section Five. If this does not rectify the problem, refer the instrument to X-Rite or an authorized service center for proper servicing. There are no user serviceable components in the sensitometer.
