Setting the Resistance Type

Two resistance types consisting of Rmeas and Ruser can be selected, with Rmeas
as the default type.
When Rmeas is selected, an externally measured bridge resistance value stored in
EEPROM will be used. This value corresponds to the current bridge resistance
setting, and is not editable via the front panel.
When Ruser is selected, you can enter a resistance value to be used in power
measurement. The value of Ruser corresponds to the current bridge resistance
setting, with a ±10% tolerance. If a value entered for Ruser exceeds the ±10%
tolerance level of the bridge resistance, the value will be clipped to the upper/
lower limit within tolerance.
You can measure the value of Ruser using the following steps:
