Using Display Hold
Press Q to enter the Display Hold mode and freeze
the present reading and its time stamp. New readings now
appear in the secondary display. See Figure 2-6. To exit
Display Hold mode, press Q again.
Note
The bar graph and secondary display may show
different units in Capacitance and Ohms due to
Autoranging.
In the MIN MAX mode, Display Hold functions like a
toggle, interrupting and resuming the MIN MAX
operations.
With Model 189, you cannot use Display Hold while
logging data. Model 189 allows you to save the frozen
reading to memory by pressing O R (SAVE).
