"RES 50.000" - main level is 50 ohms. "R:TLV 40.000" - transient level is 40 ohms.

"C:SLW.50000" - slew rate is 0.5 A/μs (middle resistance range uses the CC slew rate setting).

If you now select the low range (0 to 1 ohm, R:RNG 1.0000), the settings will automatically be changed to fit into the new range as follows:

"RES 1.0000" - main level is 1 ohm (max value low range). "R:TLV 1.0000" - transient level is 1 ohm (max value low range).

"V:SLW 5.0000" - slew rate is 5 V/μs (low resistance range uses the CV slew rate setting).

If you now select the high range (10 to 10 k ohms, R:RNG 10000), the settings will be automatically adjusted to fit into the new range as follows:

"RES 10.000" - main level is 10 ohms (min value high range). "R:TLV 10.000" - transient level is 10 ohms (min value high range).

"C:SLW .50000" - slew rate is 0.5 A/μs (high resistance range uses the CC slew rate setting).

Examples

 

The following examples illustrate how to set CR values. Before you do these examples, press

to

set the CR values to their factory default states.

 

1.Set Range

a.Press to select the CR function. Now press to determine which range is presently selected. Note that the display indicates "R:RNG" and the maximum middle range resistance value. This means the middle range is presently selected.

b. Select the low range by pressing

c.Press and check that the display indicates "R:RNG" and the maximum low range value. This means the low range is presently selected.

2.Set Main Level

a.Press and note that the display indicates "RES" and the maximum low range resistance value.

b.Set the main resistance level to 0.2 ohms by pressing

c.Press again and check that the display indicates "RES 0.2000" .

You can use ENTRY keys to increment () and decrement ( ) the RES setting. You can see the setting being incremented or decremented each time you press the applicable Input key. The values are entered automatically (you don’t press the Enter key). Remember if the CR mode is active, the incremented or decremented values will immediately change the actual input.

Note

In the middle and high resistance ranges, the resolution of the main level and transient level settings will

 

be degraded as higher values are entered. The value of resistance displayed will be the closest one to the

 

value entered. A similar effect will occur with the

and

keys.

 

 

 

 

3.Set Slew Rate-In the low range, the resistance slew rate is in volts/microsecond instead of ohms/microsecond. Whatever value is programmed for the voltage slew rate "V:SLW" is also used for resistance in the low range. In the middle and high ranges, the resistance slew rate is programmed in amps/microsecond. Whatever value is programmed for the current slew rate "C:SLW" is also used for resistance in the middle and high ranges.

a.First press the (blue shift key) and note that the Shift annunciator comes on. Now press (shifted Tran Level key) to determine the present slew setting. Note that the display indicates "V:SLW"
