Recalling Previously Recorded Readings (Recall)
Trig Hold- Log and Auto Hold- Log readings are recorded
automatically for future review or analysis by default.
Recalling readings stored in the multimeter’s memory is
performed through the key.
1 Press for more than 1 second to enter the Recall
menu. The last recorded reading is shown on the display.
The analog bar graph is used to indicate the record index.
Figure 3-7 View display
If nothing has been recorded, is displayed instead.
NOTE
• Up to a maximum of 10 records can be stored at a time. The Trig
Hold-Log and Auto Hold-Log records share the same memory space.
When the memory’s index is full, the next reading to be recorded will
overwrite the last reading recorded (the 10
th
index).
• By default, each Trig Hold-Log and Auto Hold-Log reading is stored
temporarily in the multimeter’s volatile memory. All temporary records
will be erased when the multimeter is turned OFF.
• You can choose to save the temporary records in the multimeter’s
nonvolatile memory by pressing and holding for more than 1
second. Records stored through this method remains saved even when
the multimeter is turned OFF or if the battery is replaced.
