MEMORY RECALL
The following readings are stored in memory for 5 minutes after
release of the power switch:
DT-205LR:
DT-207LR:
These readings can be recalled by pressing the memory switch.
During measurements, ten extra readings can also be captured,
stored, then recalled using the memory switch. While the tachom-
eter is in use, simply press the memory switch each time a read-
ing needs to be stored.
Contact Mode (Rate Functions)
When the rate functions are selected (mPM, YPM, FPM and 1PM),
the memory store and recall functions are accomplished exactly
as noted above.
Contact Mode (Length Functions)
When the counting functions are selected, the memory store and
recall functions are accomplished in the same manner as the
non-contact mode, the only exception being the maximum and
minimum readings (they do not exist).
Memory Clearing
To clear the memory (for all functions), press the memory switch
for approximately 5 seconds until the display shows” CCCCCC “.
Next, press the white Power switch or Memory switch. This resets
the tachometer for use.
BATTERY REPLACEMENT (2 each “M”)
Low battery voltage is indicated by flashing LOW BAT on the dis-
play. Remove end cover by using a coin or appropriate screw-
driver and replace both batteries. Please ensure proper polarity.

RANGE & ACCURACY
Place selector switch in the proper position. Using the DT-ADP-
200LR adapter and 6” master wheel, the following industrial units
of measurement are achieved:
NOTE: When using the 6” master wheel, accuracy can be affect-
ed as much as 0. 3% of reading
Although the tachometer alone is able to achieve the
above ranges, the 6” master wheel has maximum
speed limitation of 5,000 FPM (for safety reasons)
