Remote operation
Use the following commands to configure and control the average math function:
CALCulate:FUNCtion AVERage Select the average math function
CALCulate:STATe <b> Enable or disable math operations
<b> = 0 or OFF Disable math
= 1 or ON Enable math
Use the following commands to acquire the count, minimum, maximum, and average readings:
CALCulate:AVERage:MINimum?
CALCulate:AVERage:MAXimum?
CALCulate:AVERage:AVERage?
CALCulate:AVERage:COUNt?
Null
When the null feature is enabled, the displayed reading is the difference between the measured input
signal and the stored null (also called relative) value:
Displayed reading = Measured input reading - Null value
You can acquire the null (relative) value by measurement or by specifying the value. The null value is
stored in volatile memory, which will be cleared when power to the instrument is cycled.
Typical uses of the null feature:
• Cancel out test-lead resistance that can result in inaccurate low-level resistance Measurements.
The subsequent resistance measurement reading will exclude the test lead resistance.
• Establish a baseline level (such as a voltage) that will shift the measured reading. For example, if
a 5 V null level is set, the measurement of a 5 V input signal is displayed as 0 V.
The null feature is available for all functions except continuity, diode, and ratio.
The null feature and other math functions may not be used at the same time.
The null feature can be used from the front panel or by using remote operation.
