This Digital Tachometer provides fast and accurate non-contact RPM and surface
speed measurements of rotating objects.
*This tachometer is used the CPU technique, photo-electrical technique, and junction
laser technique for one instrument combined PHOTO TACH. (RPM & REV)
Two test modes: rotate speed mode (unit: RPM) & count mode (unit: REV)
Wide measure range and high resolution.
High visible digital LCD and backlight display.
Built-in memory recalls Max/Min and last value stored.

OPERATION
•
Cut the reflective adhesive tap provide into approx 12mm (0.5″) squares and apply one
square to each rotation shaft.
NOTE: The non-reflective area must always be greater than the reflective area.
• If the shaft is normally reflective, it must be covered with black tape or black paint
before attaching reflective tape
• The shaft surface must be clean and smooth before applying reflective tape.
• Depress the “MEAS” button and align the visible light beam with the applied target
• Verify that monitor indicator lights when the target aligns with the beam.
• The current mode is the last time mode used. If you need to change the mode, release
the “MEAS” button and press the “MODE” button before the instrument auto powers off
to switch between “RPM” and “REV” (revolution).
• Select the mode of you require, then press the “MEAS” to start readings.
NOTE: This instrument will auto power off in 10 sec after releasing the “MEAS” button.
• Press the “MEM” button displays the reading of the Max, Min and Last value for the
previous measurement taken.
VERY LOW RPM MEASUREMENT
• Measuring high resolution and fast sampling time is easier than measuring slow RPM.
• If measuring very low RPM values, it is suggested to attach more “REFLECTIVE
MARKS” spaced around the shaft
• Then divide the reading shown by the number of “REFLECTIVE MARKS” placed to get
the correct RPM value.
MAINTENANCE
Replacing the battery
• When the meter display fades the battery needs changing.
• Open the battery cover on the rear case.
• Remove the old battery and fit a new 9V PPA battery into the battery holder noting the
correct polarity of the connector.
• Replace the battery cover.
Cleaning
• Clean the meter with a clean, soft cloth.
• Do not use any chemicals, abrasives or solvents that could damage the meter.
