Logger
|
Radio Power |
1 mW (0 dBm) |
Transmission Range |
Approximately 30.5 m (100 ft) line-of-sight |
Wireless Data Standard |
Bluetooth Low Energy (Bluetooth Smart) |
Logger Operating Range |
-20° to 70°C (-4° to 158°F); 0 to 95% RH (non-condensing) |
Logging Range |
1 second to 18 hours |
Logging Modes |
Fixed interval (normal, statistics) or burst |
Memory Modes |
Overwrite when full or stop when full |
Start Modes |
Immediate, push button, date and time, or next interval |
Stop Modes |
When memory is full, push button, date and time, or after a set logging period |
Restart Mode |
Push button |
Time Accuracy |
±1 minute per month at 25°C (77°F), see Plot B in User Manual |
Battery Life |
1 year, typical with logging interval of 1 minute. Faster logging and/or statistics sampling intervals, entering burst logging mode, and remaining connected with the app affects battery life. Excessive readouts, audible alarms, and paging all affect battery life. Visual alarms and other events can have a marginal effect on battery life. |
Battery Type |
Two AAA 1.5 V alkaline batteries, user replaceable |
