to plot and tap OK. 

Internal Event Name 

Definition 

Host Connected 

The logger was connected to the mobile 
device. 

Started 

The Start/Stop button was pressed to begin 
or resume logging. 

Stopped 

The logger received a command to stop 
recording data (from the app or by pushing 
the Start/Stop button). 

Button Up/Button 
Down 

The Start/Stop button was pressed for 
1 second. 

Chan <#> Alarm 
Tripped 

A sensor alarm has tripped; <#> is the sensor 
number, where 1 is temperature and 2 is RH. 

Chan <#> Alarm 
Cleared  

A sensor alarm has cleared; <#> is the sensor 
number, where 1 is temperature and 2 is RH. 
This event also contains the value that was 
furthest out of range for the sensor before 
the alarm cleared, which is only available in a 
shared or exported file. 

New Interval 

The logger has entered or exited burst 
logging mode. 

Safe Shutdown 

The battery level dropped below 1.85 V; the 
logger performs a safe shutdown. 

Mounting the Logger 

There are several ways to mount the logger using the materials 
included: 

 

Use the four magnets on the back of the logger case to 
mount it to a magnetic surface. 

 

Attach Command strips to the back of the logger to 
mount it a wall or other flat surface. Double up the two 
Command strips so that they protrude past the magnets. 

 

Use the double-sided tape to affix the logger to a surface. 

 

Insert the hook-and-loop strap through the mounting 
loops on both sides of the logger to mount it to a curved 
surface, such as a pipe or tubing. 

Protecting the Logger 

The logger is designed for indoor use and can be permanently 
damaged by corrosion if it gets wet. Protect it from 
condensation. If the message FAIL CLK appears on the LCD 
screen, there was a failure with the internal logger clock 
possibly due to condensation. Remove the battery immediately 
and dry the circuit board. 

Note:

 

Static electricity may cause the logger to stop logging.

 

The logger has been tested to 8 KV, but avoid electrostatic 
discharge by grounding yourself to protect the logger. For more 
information, search for “static discharge” on onsetcomp.com. 

Battery Information 

The logger requires two user-replaceable AAA 1.5 V alkaline or 
optional lithium batteries for operation at the extreme ends of 

the logger operating range. Expected battery life varies based 
on the ambient temperature where the logger is deployed, the 
logging or sampling interval, frequency of offloading and 
connection to the mobile device, number of channels that are 
active, audible alarms duration, use of burst mode or statistics 
logging, and battery performance. New batteries typically last 1 
year with logging intervals greater than 1 minute. Deployments 
in extremely cold or hot temperatures, a logging interval faster 
than 1 minute, or a sampling interval faster than 15 seconds 
can impact battery life. Estimates are not guaranteed due to 
uncertainties in initial battery conditions and operating 
environment. 

Note:

 Make sure the batteries installed have flat negative 

terminals. There should be no indent in the bottom of the 
batteries. Batteries with indents in the negative terminals may 
become loose and prevent proper operation. 

 

To install or replace the batteries: 

1.

 

Open the battery door on the back of the logger. 

 

2.

 

Remove any old batteries. 

3.

 

Insert two new batteries observing polarity. 

4.

 

Reinsert the battery door and snap it back into place. 

 

WARNING:

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

(185°F), or recharge the lithium batteries. The batteries 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 batteries in fire. Do not expose the contents of 
the batteries to water. Dispose of the batteries according to 
local regulations for lithium batteries. 

 

 

 

Only use batteries 
with flat negative 
terminals 

Do not use batteries with an 
indent in the negative terminal
