4.6 Data hold
When in real time display mode, the data on the display
can be held at any time by pressing the REAL TIME key.
When HOLD is activated a warning message is briefly
displayed and the word HOLD appears in the top right
hand corner of the display.
Press the REAL TIME key again or the HOME key or START
key to release HOLD; in this case, HOME and START do not
have their normal functions. Changing mode also releases
hold.
When HOLD has been activated, the DSP continues to
sample, compute and filter the results but the data is
ignored by the CPU. When HOLD is released the display is
updated with the next available value from the DSP.
