Caution: When making surface speed or distance measurements, insure that the 6" circumference
wheel's perimeter is parallel to the object to be measured. Do not push the wheel against the object
with great force.
Note: When using the master wheel, accuracy can be affected as much as 0.4% of reading.
MEMORY FUNCTION
This tachometer's memory capabilities include minimum, maximum, last measurement, 10
selectable measurements and an average of the memory measurements.
1. Minimum, maximum and last measurements are recorded automatically by the tachometer.
2. Ten selectable measurements can be programmed into memory by pressing the MEM button
while the POWER button is fully depressed (M1, M2, M3, … M10).
3. The average value of sequentially stored memory, up to ten, can be viewed by pressing the
memory button.
Note: if the memory button (MEM) is not selected while the POWER button is pressed the
measurement will not be recorded into its memory location, The memory will be recorded
automatically into memory if the measurement made is the maximum, minimum or last
measurement.
To delete stored memories do one of the following:
1. Press the MEM button for five seconds or more. All memory will be erased after [CCCCC] is
displayed.
2. Changing the units of measurements and then making additional measurements.
3. Memory will be automatically erased if the TACHOMETER turns off automatically after five
minutes.
BATTERY REPLACEMENT
When "LO BAT" flashes on the display, replace the batteries with new ones.
To replace the batteries, slide the battery cover located on the rear of the tachometer. Remove the
old batteries and insert three new batteries while observing proper polarity. Replace the rear cover
of the tachometer (dispose of old batteries properly).
Notes:
1. Do not mix old and new batteries.
2. When replacing the batteries, use AA batteries.
3. The Tachometer may be damaged if liquid leaks from the batteries. This may happen if the
batteries are left inside the tachometer's enclosure for long periods of time. Remove the batteries
after using the tachometer, and store them in the carrying case.
