CALibration[1]|2:ZERO:NORMal:AUTO <boolean>
This command provides a quick way of zeroing the NORMAL path of an 
E9320 Series sensor. The average only path is unaffected. This command 
can only be used to zero an E9320 Series sensor and a P- Series sensor. 
The command causes the power meter to perform its zeroing routine, on 
the specified channel, when ONCE is selected. This adjusts the power meter 
for a zero power reading with no power supplied to the power sensor. 
The  0|OFF parameter is only required for the query response and is 
ignored in the command. If 1|ON is selected on an E9320 Series sensor, it 
causes the error –224, “Illegal parameter value” to occur.
Except when using a P- Series sensor, this command assumes that the 
E9320 Series sensor is not connected to a power source. 
Syntax
Example
NOTE
The P-Series sensor only has a NORMAL path. Hence, the reason this E9320 Series sensor 
command is allowed to function.
CAL2:ZERO:NORM:AUTO ONCE This command causes the power meter to 
perform a zeroing routine on Channel B.
