used with the PIECAL 322.

turn off after 30 minutes of inactivity to save
battery life. If AUTO OFF is OFF the unit will stay
on until the POWER SWITCH is moved to the off
position.

up. For maximum battery life turn the backlight
off when using the calibrator in areas with
enough ambient light to read the display.

EZ-CHECK (0, 50 & 100%).

in 25% increments (0, 25, 50, 75 & 100%).
