immediate resistance level automatically when a trigger is received. In CR mode, if the input of
the load is ON, the input resistance value will be updated immediately when a trigger occurs. If it
is not in CR mode, the level will not affect the load until the CR mode becomes enabled.
The triggered resistance level can only be set via remote command: RESistance:TRIGgered
<NRf+>. Once a triggered resistance level is triggered, the subsequent triggers will have no effect
on the input unless another new triggering signal is sent. The trigger operation will be described in
later chapter. The status register of the load can keep track of pending triggers and other operation
conditions, which will be described in details in

2.3.3.4 Transient Resistance Level
In transient resistance operation mode, the load can continuously toggle between the two levels:
the transient resistance level and the immediate resistance level. The transient resistance level can
be set in the transient operation menu or via the remote command: RESistance: TLEVel <NRf+>.
2.3.4 CP Test
The constant power mode is the constant power-voltage source mode, being suitable for the
voltage source test. In CP mode, the load will consume a constant power from the power source
regardless of the external current and voltage change to meet U*I=P, as shown in figure 2-4. In
basic operation state, press key to enter the mode and parameter set menu, then enter the
power value via the keypads or knob combining with and keys, finally confirm the
setting with key. The CP mode and the parameters can also be set via the remote
commands:
MODE CP
POWer <NRf+>
