Zeroing and Calibrating the P-Series Sensor
This section describes how to zero and calibrate the power meter when using a
P-Series Wideband Power Sensor.
Zeroing
Zeroing adjusts the power meter for a zero power reading on each power meter
channel and P-Series sensor combination. This is achieved without removing it
from a power source. The power meter can be set to automatically zero on-the-fly
while you are using the it. Alternatively, you can perform a zero at your preference.
During zeroing a wait symbol is displayed.
Figure 2-61 Zeroing pop-up
When the P-Series Power Sensor is initially connected to the power meter, it
automatically performs a Zero and Calibration routine.
When to Zero?
Zeroing of the power meter is recommended:
– When a 5
o
C change in temperature occurs.
– Every 24 hours.
– Prior to measuring low level signals. For example, 10 dB above the lowest
specified power for your power sensor.
Automatic Zero
The automatic zero can be enabled as follows:
Click , and toggle the to On.
