In the red box, click the icon in the yellow box and the APP starts to record the charging data.
![How to Use ChargerLAB POWER-Z KM003C Tester to Record Charging Data Online-Chargerlab](https://www.chargerlab.com/wp-content/uploads/2023/02/2023021401231924.png)
The two options in the yellow box can set the stop condition for the tester. The first option makes the recording stops after the current reaches the set minimum value, and the second option can let the current expand for a few seconds before stopping.

Sampling Rate: This allows you to set the number of data collected by the APP in 1 second. There are four options: 1SPS, 10SPS, 50SPS and 1KSPS.
Cache Depth: This allows you to set the storage space size of the APP, more storage capacity means more test data can be stored.
![How to Use ChargerLAB POWER-Z KM003C Tester to Record Charging Data Online-Chargerlab](https://www.chargerlab.com/wp-content/uploads/2023/02/2023021401232331.png)
For example, now the sampling rate is set to 1SPS, the number of data that can be cached is 100 K, and the recording time is about 27 hours.
![How to Use ChargerLAB POWER-Z KM003C Tester to Record Charging Data Online-Chargerlab](https://www.chargerlab.com/wp-content/uploads/2023/02/2023021401232613.png)
Then, let's change the sampling rate to 10SPS, the number of data that can be cached is still 100 K, but the recording time is reduced to 2 hours.
![How to Use ChargerLAB POWER-Z KM003C Tester to Record Charging Data Online-Chargerlab](https://www.chargerlab.com/wp-content/uploads/2023/02/2023021401232838.png)
Next, let's set the sampling rate back to 1SPS, and change the cache depth to 100MB. The number of data that can be cached is increased to 100 K, but the recording time is reduced to 2 hours.
![How to Use ChargerLAB POWER-Z KM003C Tester to Record Charging Data Online-Chargerlab](https://www.chargerlab.com/wp-content/uploads/2023/02/2023021401233010.png)
At present, the cache depth can be up to 1999MB, which can cache 19.99 million pieces of data and can record for 5552 hours!
