The warm-up for our products takes about 30 minutes, which is stated as part of our specification.
Measuring instruments (or power supplies) need to avoid a warm-up drift on their internal circuits or elements to ensure the machining accuracy.
Therefore, we recommend that instruments should be powered on for a certain period of time before use.
It is especially critical that the power supplies and electronic loads should be output on (or set to load on) during the warm-up to stabilize their semiconductors (e.g., power transistors) prior to calibration of the indicators.
Once the warm-up is complete, you don’t need to warm up each time you change the current value.
