O, and mbar. Features include a large
backlight display, max-min, hold, and auto power off functions. The USB
port enables communication with a computer. High accuracy of ±0.3% fs at
25ºC, repeatability: ±0.2% (max ±0.5%) FSO, and combined linearity and
hysteresis: ±0.2 (Max ±1.0%) FSO.
CAUTION: During the Zero Setting (page 4). Make sure the tube is
disconnected and do not apply pressure to the connector. Doing so can
cause permanent damage to the unit, which is not covered by the warranty.
