TIME PICKUP RANGE:
5 Amp Unit: 0.5 to 15.9 Amps in 0.1 Amp steps
1 Amp Unit: 0.1 to 3.18 Amps in 0.02 Amp steps
TIME DROPOUT:
Not less than 95% of pickup value.
TIME PICKUP ACCURACY:
± 2% of setting
TIME DIAL RANGE:
0.0 to 9.9 in 0.1 steps
TIME CHARACTERISTICS:
Nine inverse time and 1 fixed time function can be
selected by a front panel switch. Characteristic
curves are defined by the time characteristic
equation. The fixed time characteristic provides
delays of 0.0 to 9.9 seconds corresponding to the
dial setting.
INVERSE TIMING ACCURACY:
± 2%, ±1 cycle for multiples of pickup from 2 to 40.
Below multiples of 2, errors may increase directly
proportional to the value of ______.

-1)
FIXED TIME ACCURACY:
±2% or 30 milliseconds, whichever is greater.
TIME RESET:
Instantaneous or decay, internally selectable.
INST PICKUP RANGE:
5 Amp Unit: 2.0 to 99 Amps in 1 Amp steps
1 Amp Unit: 0.2 to 19.8 Amps in 0.2 Amp steps
