To Edit the Timer Parameters using Templet

The instrument provides various built-in output templets and users can select and

edit the templet as well as create timer parameters based on the templet. The

instrument will output according to the parameters currently created.

Press Timer  Timer Set and press Templet to open the templet edit menu.

1. Select the editing object

Press Edit Obj to select “Voltage” or “current”.

 Voltage: when it is selected, press Current and use the numeric keyboard

or direction keys and knob to set the current value. Then, select the templet

and edit the templet parameters. The interface displays the voltage

preview.

 Current: when it is selected, press Voltage and use the numeric keyboard

or direction keys and knob to set the voltage value. Then, select the templet

and edit the templet parameters. The interface displays the current

preview.

2. Select the templet

Press Type to select the desired templet, including Sine, Pulse, Ramp, Stair Up,

Stair Dn, StairUpDn, Exp Rise and Exp Fall.

 Sine

The Sine waveform is as shown in the figure below. The instrument

determines the Sine amplitude according to the maximum and minimum

currently set and determines the Sine period according to the total number

of points (denoted by P) and the time interval currently set, thus

determining the Sine waveform. When creating parameters, the instrument

draws P values from the preset Sine waveform according to the current

time interval.

 Pulse

The Pulse waveform is as shown in the figure below. The timer parameters

created from Pulse waveform only contain two points.

The first point: the amplitude (voltage or current) is determined by the high

level set; the time equals the pulse width currently set.

The second point: the amplitude (voltage or current) is determined by the

low level set; the time equals the period currently set minus the pulse width

currently set.
