SHIMPO DT-107A-S12 - 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-105A-S12/107A-S12 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" with an integer will
appear on the top of the display momentarily, and 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 along
with its memory position. 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 continue to show CCCCC until the switch is released, then
will default to 0.00.
Battery Replacement
Low battery voltage is
indicated by LO BAT 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. The selected
function will be shown "blinking" above the display digits.
4. Press and hold the on-off 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 5 minutes. Readings will be retained in
memory for 5 minutes and can be extended any number of
additional 5 minute periods by re-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.
2. Turn selector switch to desired unit.
CAUTION: Do not
attach master speed
wheel on extension
shaft. The wheel may slip off during measurement.
