< 10% Flashing

Note: 

Battery level is updated every 5 minutes.

Note: 

Once battery level drops to below 10%, device 

may not work properly. Replace batteries immediately.

Note:

 When replacing batteries, after removing the 

old batteries, wait 10 seconds before inserting new 

batteries. Otherwise, Bluetooth may not work properly.

MEASUREMENT READING UPDATE FREQUENCY

3.  If no connection has been made for 

ONE MINUTE

Bluetooth will be disabled to save battery life, and 

Bluetooth LCD symbol   disappears, or quick 

press twice again to disable Bluetooth. To enable 

again, go to Step (1).

HOW TO SETUP DEVICE 

Confi gure device before use

1.  Enable Bluetooth on device.

2.  Use TraceableGO™ App to connect to device.

3. 

Follow TraceableGO™ App instruction to confi gure 

device.

4. 

The following parameters are confi gured through 

TraceableGO™ App: START Mode, STOP Mode, 

ALARM Enable/Disable, Celsius/Fahrenheit, 

Memory Mode, Data Logging Interval, Alarm 

Setting.

5. 

Once device has been confi gured, device enters 

STANDBY Mode.

Note:

 While device is connected to our Traceable-

GO™ App, if no action has been taken for 5 minutes, 

device will terminate the connection from our 

TraceableGO™ App.

1.  Once an alarm is triggered by any of temperature, 

humidity out of set alarm range, LCD symbol 

LOW 

ALM

 and/or 

HI ALM

 starts to fl ash. An Alarm Event 

will be logged.

2.  Pressing 

START/STOP 

once will clear the alarm, 

LCD symbol stops fl ashing. An Alarm Acknowledge 

Event will be logged.

3.  If temperature, or humidity falls back to normal 

range, an Alarm Event will be logged. If any of 

temperature, humidity measurement goes back to 

out of alarm range, alarm will be triggered again.

HOW TO START, STOP, AND RESUME DATA 

LOGGING

1.  Devices are factory initialized with default setting:

• START Mode: Push Start

• STOP Mode: Push Stop

• 

Memory Mode: Wrap when Memory is Full

• Temperature Unit: Celsius

• Data Logging Interval: 5 minutes

• Alarm Enable/Disable: Enabled

• Alarm Setting High Alarm:

▪ Temperature: 8°C

▪ Humidity: 75% RH (6537 only)

• Alarm Setting Alarm Low:

▪ Temperature: 2°C

▪ Humidity: 25% RH (6537 only)

• Date/Time is also set to current to central time.

Note: 

Devices are shipped with battery, powered 

on, and ready to use if using default setting. Without 

powered on, device will lose track of date/time.

Note:

 If a user intends to use device for different 

setting other than default, device must be re-

initialized.
