Measurement Procedure; Preparation For Measurement - GRAPHTEC GL2000 Quick Start Manual

For example, when you are using a 4GB SD card with 100MB already used, the total capacity of the SD card is
4GB with 100MB used space, and the available space of the SD card would be approximately 3.9GB. As the
captured time elapses, the usage of the SD card increases and the remaining capacity of the SD card
decreases.
The remaining recording time indicates the remaining capacity of the SD card.
However, when the relay capturing function is set to Off, and when the remaining capacity of the SD card
exceeds 4GB, the remaining time that can be captured to 1 file will indicate 4GB.
* Remaining time which is more than 99999 hours is displayed as "++++:++:++".

Measurement Procedure

This section describes how to make capturing settings and replay captured data.
The following captured data is explained.
1CH: Sets the temperature environment using the measurement temperature and the type T
thermocouple.
2CH: Measures the voltage and fading voltage.
Sampling interval: 1 second
Data storage destination: SD card

1. Preparation for measurement

1. Connect the type T thermocouple to the screw terminal of 1CH.
2. Connect the fading voltage to the BNC terminal of 2CH.
3. Turn on the power of the main unit.
