For other error messages, refer to page 107.
● “TOO BRIGHT” (During zero calibration)
• Cause : Light is entering the measuring probe’s recep-
tor.
• Action : Block the light completely, and when “PUSH 0-
CAL KEY” appears press the 0-CAL key again
to start zero calibration.
● “E1” (After completion of zero calibration)
• Cause : “E1” is displayed if the instrument is used for
the first time since shipment from the factory,
because no target color has been set.
• For other cases, refer to page 107.
2. Zero Calibration Check Method
If you want to check whether zero calibration has been performed correctly, block entry of light into the measuring
probe’s receptor using a blackout curtain etc.
• If the message shown on the right appears in the LCD
display section, perform zero calibration again.
• Zero calibration has been completed correctly if “000”
blinks for “Lv” in the digital display section. If a value
other than “000” is displayed, perform zero calibration
again.
(Note) Even if “OFFSET ERROR” is displayed, measurement will start if the measuring probe’s receptor is exposed to light.
