When some hardkeys are selected the corresponding softkey labels are displayed on the power meter display. If you are using the power meter remotely refer to the HP E4418B/4419B Programming Guide for remote operating details.
Page 23: Turning On The Power Meter
Prior to making your ﬁrst measurement you must zero and calibrate the sensor and meter combination. Refer to Chapter 2 for further information if you are not familiar with zeroing, calibrating or making measurements with a power meter.
