SHIMPO DT-107A - Manual (Page 2)

Memory Recall
A. AUTOMATIC MEMORY
The following are automatically stored in memory for 5 minutes
following release of the power switch:
• Last reading
• Maximum reading
• Minimum reading
These readings will be displayed in the following order when
the memory switch is pressed:
• Last reading
• Maximum reading
• Minimum reading
To fill all three memory spaces, unit must operate for about 5
seconds. If any of the above memory readings are missing,
unit must operate a few seconds longer.
B. MEMORY SELECTION
The DT-107A has the capability of storing 10 extra readings in
its memory. These readings can be obtained from the same
machine or many machines (up to 10) by pressing the memory
switch momentarily as the reading you wish stored appears on
the display. An "M" will appear on the display briefly, and that
reading will be stored in memory. Up to 10 readings can be stored.
NOTE: All memory data will be erased if automatic shut-off
has occurred. To recall a specific reading, press the memory
switch until the desired reading shows up on the display
alternating with its position within the memory. To erase all
data from the memory, press the memory switch for at least 5
seconds until display shows CCCCC. If you hold the memory
switch, the display will alternate between CCCCC and 0.00.
If the memory switch is released then the display will default
to 0.00.
Battery Replacement
Low battery voltage is
indicated by a "B" on the
display. Remove end
cover by using a coin or
appropriate screwdriver
and replace both batteries.
Please note polarity.
Operating Procedure
1. Place adapter or wheel
on shaft (as shown).
3. After attaching proper
adapter or wheel, bring
it into contact with
rotating object or
moving surface whose
speed is to be measured.
Apply only enough pressure to eliminate slip. A blinking red
dot appears on the upper right corner of the display when
shaft is turning.
4. Press and hold the on-of f switch. Display will update
approximately every second.
5. Observe speed for as long as it is desired.
6. On-off switch must be released prior to removal of tachometer
from rotating object if last reading must be captured.
7. After release of power switch, the last reading will be displayed
for approximately 10 seconds. Readings will be retained in
memory for 5 minutes and can be extended any number of
additional 5 minute periods by pressing the memory switch.
Surface Speed Metric Conversion
Conversions such as YPM to mPM or mPM to YPM may be
obtained from the memory only by switching from one mode
to another.
