Limit Operations; Setting Limit Values - Keithley 2010 User Manual

3-18 Measurement Options

Limit operations

Limit operations set and control the values that determine the HI/IN/LO status of subsequent
measurements. Limits can be applied to all measurement functions except continuity. The limit
test is performed after mX+b and percent math operations. Unit prefixes are applied before the
limit test, for example:
•
•
You can configure the multimeter to beep when readings are inside or outside of the limit
range.

Setting limit values

Use the following steps to enter high and low limit values:
1.
2.
3.
4.
5.
6.
7.
8.
Low limit = -1.0, High limit = 1.0
A 150mV reading equals 0.15V (IN).
Low limit = -1.0, High limit = 1.0
A 0.6kΩ reading equals 600Ω (HI).
Press the SHIFT-LIMITS keys to view the present HI1 limit value:
HI1:+1.000000 ^
This value represents the absolute value of that function.
Use the or keys to move to the number field. Use the
enter the desired value. Move the cursor to the rightmost position (^) and use the L and
M keys to move the decimal point.
Press ENTER to view the present LO1 limit value:
LO1:-1.000000 ^
This value represents the absolute value of that function.
Enter the desired value for this low limit.
Press ENTER to view the present HI2 limits value:
HI2: +2.000000^
This value represents the absolute value of that function.
Enter the desired value for this high limit.
Press ENTER to view the present LO2 limit value:
LO2: -2.000000^
This value represents the absolute value of that function.
Enter the desired value for the low limit. Pressing ENTER returns to the normal display.
