• Depending on how the device is congured, follow prompts to enter the
ambient temperature, humidity (0-99%), pressure (25-31 inHg or 850-
1060 hPa-mbar) and altitude (1-8500m). Enter these values using the
touch panel or keypad.
• Pump air through the owhead to bring it to ambient temperature.
• If the owhead has very recently been used for testing or has come
from a cold environment, its temperature should be equilibrated with
ambient by pumping air through it from the syringe several times.

on-screen instructions.
• If an Accuracy Check report is required, select the Report option.

calibration. Selecting to update calibration repeats the accuracy check routine on
the device.
