2 RECEIVING FUNCTIONS

2.2.4  Setting the Unit

 (See Section 4.3 of the instruction manual for the VR200.)

Format: SNp1, p2

p1:

Channel number (CC)

p2:

Engineering unit (up to six characters)

Example: SN02, kg

This example assigns the unit “kg” to channel 2.  Note that a unit can only be
assigned to channels of the SCL or SQRT input.

2.2.5  Setting the Waveform Span Rate (TIME/DIV)

(See Section 4.4 of the instruction manual for the VR200.)

Format: SWp1

p1:

Select the waveform span rate from 1, 5, 10, 20, 30, and 60
(minutes).

Example: SW1

This example sets the waveform span rate to 1 minute.

2.2.6  Setting the Clock

(See Section 4.5 of the instruction manual for the VR200.)

Format: SDp1, p2

p1:

Date (YY/MM/DD)
YY: The last two digits of the Western year
MM: 01 to 12
DD: 01 to 31

p2:

Time (HH:MM:SS)
HH: 00 to 23
MM: 00 to 59
SS: 00 to 59

Example: SD96/03/13, 15:02:00

2.2.7  Copying the Channel Settings

 (See Section 4.6 of the instruction manual for the VR200.)

Format: SYp1, p2

p1:

Channel number (CC) from which you want to copy the settings
(origin)

p2:

Channel number (CC) to which you want to copy the settings
(destination)

Example: SY01, 03

This example copies all settings from channel 1 to channel 3.

Note

You can only copy from a lower channel number to a higher channel number.
