before attaching reflective tape. Shaft surface must be clean

and smooth before applying reflective tape.

(4-2) Very low RPM measurement: as it is easy to get high

resolution. If measuring the very low RPM values, suggest

user to attach more “REFLECTIVE MARKS” averagely.

Then divide the reading shown by the number of

“REFLECTIVE MARKS” to get the real RPM.

(4-3) If the instument is not to be used for any extended period,

remove batteries.

1.FEATURES

※ It is used the microcomputer (CPU) technique and junction

laser technique for one instrument combine PHOTO TACH.

(RPM)

※ Wide measuring range and High resolution.

※ Auto emerald green backlight makes sure that tachometer can

work normally in any light circumstance.

※ The last displayed may be automatically stored in memory and

10s of measured value According to user needs .So this makes

customers collected and recorded data .(The tachometer starts

to store the data measured after which is renovation for three

times).

※ Low battery voltage indication.

※ The instrument is delicate and rugged .It uses the

durable .long-lasting components and a strong, light weight

ABS plastic housing .The housing has been carefully shaped to

fit comfortably in either hand.

2.SPECIFICATION

※ Display:5digital,13mm(0.5’’ Emerald green backlight LCD )

※ Accuracy : ±(0.05 ％ +1digital)Sampling Time:1sec (over6

the applied target. Verify that the MONTOR INDICATOR lights

when the target aligns with the beam.

d. It will display RPM value when display value stabilized.

(3) TOTAL MEASUREMENT

a .Apply a reflective mark to the object being measured . push the

function switch to display “0 ” on LCD.

b. Press measuring button, then you see light beam in line with the

target, start measuring. The value will add 1 as the object rotate a

circle or passed one reflective mark, herein, the total value will

stored in the meter until loosen the button.

(4) Reminds

(4-1) Reflective mark: cut and peel adhesive tape provided into

approx. 12mm(0.5’’)squares and apply one square to each

rotation shaft. 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

4.Measuring procedure

(1) ATTENTION BEFORE MEASURING

(1-1) When it is necessary to replace the battery(2 cell battery

voltage less than approx. 2.4V, “ ” will appear on

the display).

(1-2) Remove the screws of the battery cabinet by a screwdriver.

Slide the battery cover away from the Instrument and

remove the battery.

(1-3) Install the batteries into the case Permanent damage to the

circuit may result from incorrect installation.

(1-4) Don't illuminate other people's eyes with the laser and Laser

radition do not stare into beam.

(2) RPM MEASUREMENT

a .Apply a reflective mark to the object being measured . press

the TEST

button to tun on.

b .press the UNIT button to display “RPM ” on LCD.

c .Depress the TEST button and align the visible light beam with

Data Memory Explain

(1) The tachometer has ten groups of storage units, from DATA 0

to DATA 9, such as shown on the display DATA 5, said the current

is the DATA 5 storage unit , the measurement DATA of the

current will be stored in a DATA 5 storage unit, the tachometer can

be stored in the DATA of the maximum and the minimum , and the

last time the measured average.

(2) Data stored button operation

3

(2-1) Display last value before turning off the TEST button .

Continuous press MEM button, according to sequence

display MAX DATA or MIN DATA ,and AVG DATA of the

current storage unit., after display AVG DATA, And then

press the MEM, display the next data storage unit

(2-2) Press DEL button, clear all storage unit.

Reminds: AVG DATA will be AVG DATA of last measuring

data , But MAX DATA or MIN DATA is a data of all measuring

DATA. If you measure MAX DATA or MIN DATA of last measuring,

please Press DEL button to clear all DATA.

If you want to store measurement DATA in the storage unit of

DATA 5, please push the MEM button long, display will cycle DATA

0 to DATA 9, when display DATA 5, stop push MEM button, this

time measurement, the DATA is stored in the storage unit of DATA

5.
