Definition
With dBm selected, a voltage measurement is displayed as the level of power, relative to
1 milliwatt, dissipated through a reference resistance. The reference resistance is
adjustable in DL-2060. The calculation of dBm is defined as below:

Z
is the reference resistance.
※
Note: Change of reference resistance will not affect the stored relative reference value.

The Zref is adjustable with a range from 50Ω to 8000 Ω. The default value is 600 Ω.

The user selected reference value is stored in a volatile memory and will be cleared
after the multimeter has been power-off.

This feature is available for DCV and ACV only.
How to set the reference resistance
User can set the reference resistance either through the front panel operation or the
