Setting Up Limit (Boundary Value) Of Low C Reject Function - Keysight E4981A User Manual

Sorting Based on Measured Results (Comparator Function)
Rejecting Excessively Low Measured Results (Low C reject function)

Setting up limit (boundary value) of Low C reject function

Set up the limit of the Low C reject function (boundary value of the range to
detect Low C) as a percentage of the measurement range (full scale). The
applicable measurement range varies depending on the setting of the
measurement range mode:
•
•
For example, if you make a measurement with the 1 μF range fixed and set the
limit to 1%, Low C is detected when the measured primary parameter value (Cs
or Cp) is equal to or less than 10 nF.
Setup procedure
Step 1. Press [Meas Setup].
Step 2. Use the cursor key to select the LOW C REJ field.
Step 3. Use the entry keys or softkeys to enter the limit value. When you enter the
value with the entry keys, the softkey unit label changes to (%).

Keysight E4981A 120 Hz/1 kHz/1 MHz Capacitance Meter
For the auto range mode
The minimum measurement range is applicable regardless of whether the
measurement is actually performed. Specifically, it is one of the following
measurement ranges:
When measurement frequency is 120 Hz: 10E
When measurement frequency is 1 kHz: 100E
When measurement frequency is 1 MHz: 1E
For the fixed range mode
The measurement range currently selected is applicable, that is, it is the
range in which the measurement is actually performed.
