To retrieve other triple sets of measurements in either order (newest to oldest, or oldest to

newest), use the � and � buttons, respectively. For example, if the first set of values

retrieved (the most recently stored) is tagged

DATA2, pressing the � button would retrieve

the values stored in memory location DATA1. These represent the next oldest measurements,

compared to DATA2. To continue retrieving data using a reverse timeline (newest to oldest),

continue to press the � button.
To retrieve measurement data using a forward timeline (oldest to newest), use the � button.
Whichever timeline you choose, when you reach memory location DATA0 (either by moving

up from DATA9 or down from DATA1) the display will change radically.

DATA0 RECALL will

appear on the bottom line and all three readouts will show dashes instead of measurement

values and units. That’s because DATA0 is a non-storing memory location. In addition, the

letters

CL and CLE will be superimposed on the dashes of the secondary and primary

readouts. Also, the words “

Memory Space CLR-Memory” will appear in the space between

CL and CLE.
This unique display gives you the opportunity to bulk-erase the meter’s nonvolatile memory.

To do so, press the

button. This will cause the entire primary readout (the letters

CLE

superimposed on dashes) to flash continuously, indicating that all stored measurements have

been erased. To confirm the erasure, repeatedly press either the � or � button and note

that all

DATA [X] RECALL displays now show three readouts with dashes rather than

measurement values.
To return the meter to normal measurement mode after bulk-erasing the nonvolatile

memory, press the

MODE SET button.

USING THE ADVANCED SETTINGS MENU

Pressing and holding the

MODE SET button for 3+ seconds opens up the meter’s second

multi-option menu, the Advanced Settings Menu. Figure 8 is a flowchart of the options made

available from this menu by subsequent brief presses of the

MODE SET button. Once you

have entered the Advanced Settings Menu (indicated by the word

SET on the bottom line of

the display), moving to the next box down the flowchart requires only a brief press of the

MODE SET button. Pressing and holding the MODE SET button exits the Advanced Settings

Menu and returns the meter to operating in normal measurement mode.
Unlike the first virtual menu accessible from the

MODE SET button, the Advanced Settings

Menu gives you only six seconds to choose an option at each decision box moving down the

flowchart. If no button is pushed within six seconds, the menu closes and the meter resumes

operating in normal measurement mode. Once you gain experience using the meter, you will

find that six seconds is sufficient to exercise any option presented by the menu.
