alarm limits are set to the closest value supported by the

logger.

c. Under Raise Alarm After, select the duration before an

alarm is tripped and tap Done in the Alarm Duration.

d. Select either Cumulative or Consecutive Samples. If you

select Cumulative Samples, then the alarm will trip when

the time the sensor is out of range over the course of the

deployment is equal to the selected duration. If you

select Consecutive Samples, then the alarm will trip when

the time the sensor is continuously out of range is equal

to the selected duration. For example, the high alarm for

temperature is set to 85°F and the duration is set to 30

minutes. If Cumulative is selected, then an alarm will trip

once a sensor reading has been at or above 85°F for a

total of 30 minutes since the logger was configured;

specifically, this could be 15 minutes above 85°F in the

morning and then 15 minutes above 85°F again in the

afternoon. If Consecutive is selected, then an alarm will

trip only if all sensor readings are 85°F or above for a

continuous 30-minute period.

e. Tap Done in the Temperature Alarms screen. Back in the

Configure screen, a setting to maintain the alarm until

the logger is reconfigured is enabled automatically. This

cannot be disabled.

while logging (the alarm LED will not blink if an alarm trips).

You can temporarily turn on LEDs when Show LED is

disabled by pressing the button on the logger for 1 second.

11. Enable or disable Power Saving Mode. If Power Saving

Mode is disabled, the logger will “advertise” or regularly

send out a Bluetooth signal for the phone or tablet to find

via HOBOmobile while it is logging, which uses battery

power. When Power Saving Mode is enabled, the logger will

only advertise during logging when you press the button on

the logger to wake it up, thereby preserving as much

battery power as possible.

12. Tap Start in the upper right corner of the Configure screen

to load the settings onto the logger.

Logging will begin based on the settings you selected. See

Deploying the Logger for details on mounting and see Reading

Out the Logger for details on downloading.

If the logger was configured with alarm settings, an alarm will

trip when the temperature reading is outside the range

specified in the logger configuration. When an alarm trips, the

logger alarm LED blinks every 4 seconds (unless Show LED is

disabled), an alarm icon appears in the app, and an Alarm Out

of Range event is logged. Even if the temperature reading

returns to a normal range, the alarm indicator will not clear in

the app and the alarm LED will continue to blink.

Setting a Password

You can create an encrypted password for the logger that will

be required if another phone or tablet attempts to connect to

it. This is recommended to ensure that a deployed logger is not

mistakenly stopped or purposely altered by others. This

password uses a proprietary encryption algorithm that changes

with every connection.

To set a password:

1. Tap the HOBOs icon and connect to the logger.

2. Tap Logger Password.

3. Type a password up to 10 characters.

4. Tap Save.

Only the phone or tablet used to set the password can then

connect to the logger without entering a password; all other

mobile devices will be required to enter the password. For

example, if you set the password for the logger with your tablet

and then try to connect to the device later with your phone,

you will be required to enter the password on the phone but

not with your tablet. Similarly, if others attempt to connect to

the logger with different devices, then they would also be

required to enter the password. To reset a password, connect

to the logger, tap Set Logger Passkey, and select Reset to

Factory Default or press the button on the logger for 10

seconds.

Reading Out the Logger

To download data from the logger:

1. Tap the HOBOs icon and tap the logger to connect to it. If

the logger was configured with Power Saving Mode

Battery Information

The logger uses one CR2450 non-replaceable lithium battery.

Battery life is 1 year, typical with a logging interval of 1 minute,

but may be extended to two years when the logger is

configured with Power Saving Mode enabled. Expected battery

life varies based on the ambient temperature where the logger

is deployed and the frequency of connections, downloads, and

paging. Deployments in extremely cold or hot temperatures or

a logging interval faster than 1 minute can impact battery life.

Estimates are not guaranteed due to uncertainties in initial

battery conditions and operating environment.

WARNING: Do not cut open, incinerate, heat above 85°C

(185°F), or recharge the lithium battery. The battery may

explode if the logger is exposed to extreme heat or conditions

that could damage or destroy the battery case. Do not dispose

of the logger or battery in fire. Do not expose the contents of

the battery to water. Dispose of the battery according to local

regulations for lithium batteries.
