Pulse amplitude Adjustable, 0~70mA peak to peak at 1000
ohm Load each channel, 1mA/Step.
Pulse Rate Channel 1 – Fundamental frequency: 4000
Hz fixed
Channel 2 – Selectable frequency: 4001 to
4150 Hz

P1
The pulse rate of the CH1 is fixed in
4000Hz; CH2 pulse rate is increased from
4001Hz to 4010Hz in a cycle time, and then
decreased from 4010Hz to 4001Hz in nest
setting cycle time. In this program, CH2
interference frequency is varied from 1Hz to
10Hz, cycle time (5 to 30 sec) is fully
adjustable.
CH 2 pulse rate=4000Hz+ Interference
frequency
P2
The pulse rate of the CH1 is fixed in
4000Hz; CH2 pulse rate is increased from
4001Hz to 4150Hz in a cycle time, and then
decreased from 4150Hz to 4001Hz in nest
setting cycle time. In this program, CH2
interference frequency is varied from 1Hz to
150Hz, cycle time (5 to 30 sec) is fully
adjustable.
CH 2 pulse rate=4000Hz+ Interference
frequency
P3
The pulse rate of the CH1 is fixed in
4000Hz; CH2 pulse rate is increased from
4080Hz to 4150Hz in a cycle time, and then
decreased from 4150Hz to 4080Hz in nest
setting cycle time. In this program, CH2
interference frequency is varied from 80Hz
to 150Hz, cycle time (5 to 30 sec) is fully
adjustable.
