6.4.1.11. Peak voltage measurement
GENERAL
The adjustable trigger level with the trigger (GATE) indication offers the possibility to measure peak voltages.
Measuring peak voltages is done in the trigger level function. This means that the peak voltages are measured
with the accuracy of the trigger level function.
The order fpr measuring the peak voltage of a signal is as follows:
— Selection of the sensitivity range
; — Selection of the trigger level
— Measurement of the peak voltage
PEAK VOLTAGE MEASUREMENTS
Selection of the sensitivity ranges
— Select function V-r-r-r- with the function selector.
— Select the automatic ranging mode by depressing the AUTO/MAN*

Remark:
Manual ranging is indicated with * on the display.
— Connect the voltage source to the 0 and V terminal and measure the input signal.
— Make a note of the selected range and polarity. Slow signals may pass more than one range.
— Select function trigger level with the function selector, and select one of the noted ranges and polarity.

Remark:
Function trigger level has four ranges.
