DC Calibration

The internal DC calibration adjusts the potentiostat’s voltage and current measurement channels to compensate for temperature-related drift.

All Zahner instruments require at least 30 minutes of warm-up time before you begin taking measurements. This warm-up period is essential for the instrument to reach optimal precision and stability.

After the warm-up period, we recommend performing a DC calibration to ensure measurement accuracy. The IM7 performs this internal DC calibration automatically upon execution of the command, no external connections are required. This calibration must always be explicitly initiated and is never performed implicitly.

Without proper calibration, measurement precision may be compromised. Additionally, performing DC calibration on a cold device will result in lower quality measurement data. Calibration takes approximately three to five minutes, depending on the number of add-on cards used.
