III. PANEL DESCRIPTION (FIG.1) IV. OPERATION INSTRUCTIONS

1. Photoelectric window used in non-contact speed mode.

2. LCD screen.

3. [Measurement Key]: Press the button to start the

measurement and release to stop.

4. [Switch Key]: Switch between three modes:

a. Non-Contact Speed.

b. Contact Speed.

c. Contact Surface Speed.

5. [Power key/View button]: Long press to turn on/off;

short press [View] to store data.

6. Contact shaft assembly in contact mode.

7. Contact surface speed accessorie (surface speed wheel).

• Power on/off: Press and hold the [Power Key] for 2 sec.,

the meter is turned on, and the screen display value is 0.

Default mode of the meter is [Non-Contact Speed], in this

mode, press [Measurement Key] to emit red light

(NOTE: Do not aim at eyes).

Long press [Power Key] for 2 sec. to shut down.

• Mode switching: Long press [Switch Key] once to switch

from [Non-Contact Speed] to [Contact Speed]. At this time,

the characters displayed on the LCD screen will be reversed

so that the characters seen during contact measurement

are also positive. If you press and hold this key once again,

it will switch to [Contact Surface Speed], and so on.

• Measure

1. [Non-Contact Speed] Rotation speed measurement

(default mode when power-on)

a. Install the battery and press the [Power key], choose

[Non-Contact Speed]. Then add a piece of reective

tape on the object you wish to measure and then turn

it on.

b. Press the [Measuring Key] on the right to make the

red light beam irradiate the measured target vertically

(the part where the reective paper is attached), the

measurement starts, and the measured value is dis-

played (see Fig. 7).

c. After the displayed value is stable, release the [Me-

asuring Key]. The display now shows the last value

and multiple measurement data has been automati-

cally stored in the meter, and the measurement ends.

2. [Contact Speed] Rotation speed measurement.

a. Install the contact measurement accessories and

switch the meter mode to [Contact Speed]. At this

time, the displayed characters are automatically

turned over.

b. Press the rubber head contacting the rotating shaft

with the measured object and ensure that it rotates

synchronously and coaxially with the measured object

(see Fig. 8).

c. Press [Measuring Key] to start measurement, and

release [Measuring Key] after the displayed value is

stable, the measured value is automatically stored,

and the measurement ends.

3. [Contact Surface Speed] Surface speed measurement

(see Fig. 9).

a. Install the measuring surface speed wheel and switch

the mode to [Contact Surface Speed]

b. Hold the surface speed wheel to the measured object

and ensure that it moves synchronously with the

measured object.

c. Press [Measuring Key] to start measurement, release

it after the displayed value is stable, the measured

value is automatically stored, and the measurement

ends.

d. The meter automatically saves the measured value

during the measurement process, about 25 data per

minute. If more data needs to be stored, the measure-

ment time is lengthened.

V. DATA STORE AND VIEW

1. After the measurement is completed, release the [Mea-

surement Key], and the meter retains the display of the last

value.

The maximum value, minimum value, last value and multi-

ple instantaneous values have been automatically stored in

the instrument. Short press the [Power] key again, and the

stored measurement values will be displayed separately.

2. [View stored data]: After nishing the measurement, short

press the [Power Key] several times to complete the cycle

[View] operation

a. Short press [Power Key] once:

Display the max. value Up, as shown in Fig. 2.

b. Short press [Power Key] once again:

Display the min. value Dn, as shown in Fig. 3.

c. Short press [Power Key] once again:

Display the last value Last, as shown in Fig. 4.

d. Short press [Power Key] once again: Display the total

number of stored instantaneous values. An 7 me-

ans that there are 7 instantaneous values to view, as

shown in Fig. 5. Note: The number 7 is an example.

e. Press [Power Key] again: Display the instantaneous

value index number 1, and automatically jump to the

corresponding instantaneous value after 1 second, so

press [Power Key] several times until the last value,

and then return to the display of starting point of

above sequence as shown in Fig. 6.

3. Data clearing: Press [Measurement Key] once, all saved

data are cleared to 0.

First the index number is displayed and then the value:

Ie. the instantaneous value of No. 1 = 350.3 RPM.

Reminder: The above and the gures are examples

of [View] data in [Non-Contact], [Contact Speed]

and [Contact Surface Speed].

VI. AUTOMATIC SHUTDOWN AND BATTERY REPLACEMENT

VII. PRECAUTIONS

1. If the meter is not in use, it will automatically switch off

after ve minutes!

2. When the battery power is too low, the battery symbol

[ ] will appear on the left side of the display,

indicating that the voltage is too low and the

batteries needs to be replaced.

3. Open the battery back cover and remove the old batteries.

4. Replace with 3 × 1.5V AA batteries according to the polarity

marks on the case.

5. If the meter will not be used for a long time, please remove

the batteries to avoid battery leakage and damage to the

meter.

1. Use of reﬂective marks: The area of reective tape should

not be too small, cut a square reector with a width of about

12 mm and attach it to the rotating shaft.

In case the shaft is obviously reective, it must be painted or

covered with black tape. Add the reective tape on the shaft

afterwards.

Note: When sticking reective tape, the surface of the shaft

should be smooth and clean. See the schematic as shown

in Fig. 7.

2. When measuring at low speed, in order to improve the

measurement accuracy, it is recommended that the user

paste several reective tapes evenly on the measured object;

divide the displayed data by the number of reective tapes

to get the actual measurement value.

3. The contact speed measurement accessories are divided

into large cone, small cone and cylindrical three types, of

which large conical and cylindrical rubber parts are suitable

for low speed measurement; small cone rubber ttings are

suitable for high speed measurement.
