Page 68: Adjustment Using Display And Trimmers
User's Guide _______________________________________________________________________ The adjustment of temperature measurement is always a simple 1-point offset correction. The 1-point humidity adjustment of the HMW90 series adjusts both offset and gain, depending on the adjustment condition. In a dry condition (for example, 11 %RH), offset is adjusted more than gain. NOTE The 1-point humidity adjustment requires that the target condition is at least 50% of the currently measured value. -
Page 69: Adjustment Using An Hm70
Adjustment Using an HM70 Connect the HMW90 series transmitter to the HM70 hand-held meter using the connection cable (Vaisala order code 219980). Depending on the connected devices, you may be prompted by the HM70 meter to check the currently applied environment settings. -
