A live value is displayed in the lower left corner of the screen. The live value is the average volt- age, recalculated and updated four times per second. Note! To ensure functionality and safety, only use Volt cables provided by RaySafe. To get other measurement parameters, in addition to voltage (V) and time (s), select an appli- cable conversion factor. - Page 43 RaySafe X2 – VOLT Press Activate to make the instrument ready for measurements. The instrument will automatically perform a zero adjustment, which means that a new zero level is set, based on the voltage measured during activation. The voltage must be stable during the activation.
