Action
Press and hold the Power button.
Charge battery / plug in to USB port.
1. Unplug the USB connection.
2. Hold down on/off button 10 seconds to turn off
then restart.
Make sure you keep the instrument on the
sample until the end of the measurement.
Shield the sample to keep light from entering the
optics during a measurement on very rough or
curved samples.
On transparent samples try to prevent light from
entering the samples from sides or back. Place
sample on a white background.
Recalibrate the instrument using the Calibrate
function in the Settings menu.
You will need to perform seven calibration
procedures in a row. This will set a new reference
point and correct the problem.
Increase the volume in the Settings menu.
Make sure you hold down the Enter button during
recording.
