3-11 Operating Arithmetic Functions

Using dBm Modifier
The dBm measurement is used for decibel conversion of power per 1mW
consumption into a 600 Ω load and can be applied to Vdc, Vac and
Vdc+Vac measurements only. Voltage measurement is converted to dBm
by using the following formula:
dBm = 10x log
then followed by
The meter will displays the dBm modifier on the primary display and the
reference impedance will be indicated and flashed on the secondary
display within 3 seconds. The default value by factory is 600 Ω .
In dBm modifier mode, press
impedance desired, the reference impedance will be indicated and flashed
on the secondary display within 3 seconds. The new setting value will be
kept until power off.
Any of the following 21 types of reference impedance may be selected:
8000 Ω , 1200 Ω , 1000 Ω , 900 Ω , 800 Ω , 600 Ω , 500 Ω , 300 Ω , 250 Ω ,
150 Ω , 135 Ω , 125 Ω , 124 Ω , 110 Ω , 93 Ω , 75 Ω , 50 Ω , 16 Ω , 8 Ω , 4 Ω , 2 Ω
