E - IEC Mode Command Summary

CALCulate:LIMit:UPPer

This command sets various limits associated with rms voltage fluctuations testing for IEC 1000-3-3. as described in the following table. All five parameters are type NRf. The order in which the five parameters are entered must correspond to the order in the table.

vss delta

dmax limit

Sets the maximum peak-to-peak variation of relative voltage1 that defines “steady-state”. At *RST this value is set to 0.0032. Note that this number is not specified by IEC 1000-3-3.

Sets the maximum relative voltage1 change allowed before a dmax error is flagged. At *RST this value is set to 0.04 (see note 2).

dc limit

dt tlimit

dt limit

Sets the maximum relative steady-state voltage change allowed before a dc error is flagged. At *RST this value is set to 0.03 (see note 2).

Sets the maximum time in seconds that the relative voltage1 can exceed the dt limit before a dt error is flagged. At *RST this value is set to 0.2 seconds.

Sets the maximum relative voltage1 that must be exceeded for dt tlimit

seconds before a dt error is flagged. At *RST this value is set to 0.03 (see note 2).

1The expression “relative voltage” as used above is the measured rms voltage divided by the programmed voltage.

2This value is the ratio with respect to Un (the European nominal line voltage). For example, a value of .03 represents 6.9 volts if Un = 230 volts. (Ratio * 100 = % of Un )
