Options

-LDe: Pulse/Ramp Sequence

Following output controls of A to E are applicable.

This Option can be selected only on R4GT10-0.01, R4GT18-0.1, R4GT18-0.2, R4GT36-0.1, R4GT36-0.2.

A. Pulse Sequence

A. Pulse Sequence

ta, tb, tc and toff can be set in 0.0s to 9999h59m59.9s, respectively

Sequential operation is possible by using voltage and current set on each memory a, b and c in combination with multi-set function. Not only continuous operation, but also it is possible to specify the times. It is best fit to evaluation tests for products as various operations, like as repeat of a and b only or repeat of b, c and off only, are enabled by setting time of memory a, b, c or off to 0.0.

B. Ramp

B. Ramp

t1 and t2 can be set to 0.0 to 9999 h 59 m 59.9 s, respectively

It enables to make ramp action up to set voltage or current (or from the set voltage or current to 0V or 0A). It is useful to like to rise (reduce) voltage or current slowly.

* For ramp action, it is possible to select [both of set voltage and current] , [only set voltage] or [only set current].

C. Pulse Sequence + Ramp

C. Pulse Sequence + Ramp

t1 to t4, ta to tc and toff can be set in 0.0 s to 9999 h 59 m 59.9 s, respectively

It is also possible to use pulse sequence combined with ramp action. If multi-set function is combined with the too, it is able to make sequence action by using voltage or current set on memory a, b and c. Not only continuous operation, but also it is possible to specify the times.

It is useful in various aspects as it is possible to rise (reduce) voltage or current slowly up to 20 set value.

D. Delayed Trigger Ramp

Delayed Trigger Ramp

* t1 and t2 can be set in 0.0s to 99.9s, respectively.
* ton can be set in 0.1s to 9999h59m59.9s and toff can be set in 0.0s to 9999h59m59.9s

This is one of the combinations with Delayed Trigger Function and Ramp Function, after OUTPUT is made ON, ramp output is started in time delayed.

E. Master Follow

E. Master Follow

Pulse sequence actions at master-slave and output signal to slave units at ramp action are transmitted. By this function, it is possible to make slave units to output on different output condition from the master unit.
