You can perform a one-point calibration and adjustment with Vaisala handheld meters that utilize the MI70 measurement indicator (for example, HM70).
Connecting to the service port using a computer and a terminal program allows you to perform calibration and adjustment tasks using serial commands. You can, for example, perform a two-point humidity calibration and adjustment, or clear the existing user adjustments (factory calibration will remain).
| If you replace the HUMICAP® humidity sensor of the transmitter, you must perform the two-point humidity calibration afterwards. |
