C0 — For shippers

Note: This guide also applies to C1.

Important: DO NOT remove the plastic bag unless you need USB access for final readings.

Start the device

Watch: How to start (video)

1. Press and hold the button for 5 seconds until both LEDs light up.
2. For the first 30 minutes, the blue LED blinks twice every 2 seconds.
3. After 30 minutes, the LED stops blinking to save battery.
4. To confirm the logger is still active, press the button once. If the LED blinks, the device is running.
5. While logging, a single press creates a MARK (blue LED on for 1 second). You can make up to 8 marks.
6. The logger cannot be stopped manually; it stops when the data limit is reached.

Why is there no stop button?

Place in the shipment

Watch: How to deploy (video)

When possible, use two loggers for the simplest temperature mapping:

1. Place one at the container air outlet to record supply-air temperature from the refrigeration unit.
2. Place one at the container door to capture temperature coverage across the load.

Keep each logger in its plastic bag during transport.

Receiving side
