SETUP MODE Turning the Unit On/Off 1. Press POWER to turn the meter on. 2. Press and hold POWER for 2 seconds to turn the meter off. Selecting the Function 1. Press and hold FUNC to cycle through the options listed below.
MEASUREMENT PROCEDURES Air Velocity and Air Temperature 1. Press POWER to turn the meter on. 2. Plug the anemometer probe plug into the anemometer probe input socket. 3. Press and hold FUNC to cycle through the options until ″An″ appears on the LCD. Release the FUNC button. 4.
MEASUREMENT PROCEDURES 5. ″K" or " J″ appear on the LCD to indicate the type of thermometer. Note… When using the meter for the first time, the meter will default to K type thermocouple. See page 13 for instructions on selecting the thermocouple type.

DATALOGGER 2. If the datalogger is being used for the first time, a new file AMA01001.XLS will be generated under the route AMA01\. After exiting the datalogger and executing the function again, the data is saved to the AMA01001.XLS file until the data reach 30,000 data columns. A new file will then be generated (i.e., AMA01002.XLS).
BATTERY REPLACEMENT This meter uses six AA (1.5 V, UM3) batteries. When the low battery indicator appears on the LCD, battery replacement is needed. After the icon appears on the LCD, in-spec measurement can still be made for several hours before becoming inaccurate.
