Secondary Function Key
The secondary function key is used to enable the dual display mode, quickly
store the current instrument settings in co-ordination with and quickly enter
the REL setting interface.
1. Turn On the Dual Display
This mode enables you to simultaneously measure both voltage or current
and frequency of an ac signal. The voltage or current value is shown on the
main display, while the frequency is shown on the vice display.
For example, press
to enter the following interface.
Note:
The multimeter measures the two parameters at the same time and the
main and vice displays update respectively.
If the measurement from the main display uses math operation (STA
<MAX, MIN, AVG, ALL>, P/F, dBm, dB), turning on the vice display will
automatically disable the math operation in use, while the vice display
presents the measurement value of the vice display function.
The math operation (MAX, MIN, AVG, dBm, dB, REL) only works with the
main display when dual display function is used. Turning on P/F will
automatically disable the dual display.
If the measurement on the main display uses math operation (REL),
turning on the vice display will not change the display result on the main
display and the vice display presents the measurement value of the vice
display function.
2. Quickly Store Current Settings
Press Setn, the multimeter stores the current measurement
configurations into the memory unit corresponding to the key with the name
“Setn”. You can also use
