Turning On the Power
1. Set the power switch to the ON position (“|”).
● If the HOLD button is in the RUN position (popped out) when you
turn on the power, the CHROMA METER begins taking measure-
ments immediately.
● If the HOLD button is in the HOLD position (pressed in) when you
turn on the power, the CHROMA METER will not begin taking
measurements until the you pop the button out.
Zero Adjustment
The CHROMA METER performs zero adjustment automatically when the power comes on.
● The display shows the letters “CAL” to indicate that zero adjustment is in progress. The
“CAL” indication goes off when this adjustment is completed.
● This adjustment is carried out electronically. There is no need to attach the cap.
Battery Alarm
↓
When batteries start to run low, a battery mark appears above the
measurements on the display. As batteries run lower still, the mark
will begin to blink—at which time the CHROMA METER will no longer
be able to take measurements. Replace the batteries to restore nor-
mal operation.
● Fresh alkaline batteries should provide enough power at
least 60 hours of continuous measurements (at room tem-
perature).
When replacing batteries: Remove both of the old batter-
ies first, and then install the new batteries.
