1. Product Introduction

Thank you for purchasing the Digital Tachometer.

The Digital Tachometer is Contact and Non-Contact

RPM (revolutions per minute) measuring instruments.

Features include a 5 digits LCD, scan/hold function

and auto power off (30 seconds). To measure, point

the Laser spot or bring the contact probe to the object.

Press the measuring trigger and hold on till the reading

is stable and end of shot.

measurements, 10 selectable MIN measurements,

Use of controls or adjustments or performance of

procedures other than those specified here may

result in hazardous radiation exposure.

Do not look at the laser beam coming out of the lens

or view directly with optical instruments - eye damage

can result.

Length Measurement

You may receive harmful laser radiation exposure if

you do not adhere to the warnings listed below:

Read the following safety information carefully before

attempting to operate or service the meter. Only qualified

personnel should perform repairs or servicing not covered

in this manual.

2. Safety Information

Do not look directly into the laser beam. Permanent

This product contains a Class 2 laser; use caution

when operating this device with the laser on.

Do not submerge the unit in water.

Do not use an extension shaft as the adapters may

come off of the shaft and cause damage or injury.

If operating arrangements are used or procedures

carried out other than those described here in these

instructions, this can lead to dangerous exposure to

radiation.

2-2 Cautions!

2-3 Symbols

Dangerous, refer to this manual before using the meter.

CE Certification.

This instrument conforms to the following standards:

EN61326:Electrical equipment for measurement, control

and laboratory use.

IEC61000-4-2:Electrostatic discharge immunity test.

IEC61000-4-3:Radiated, radio-frequency, electromagnetic

field immunity test.

IEC61000-4-8:Power frequency magnetic field immunity

test.

IEC60825-1:Safety.

Tests were conducted using a frequency range of 80

1000MHz with theinstrument in three orientations. The

average error for the three orientationsis ±0.5℃ (±0.1℉)

at 3V/m throughout the spectrum. However, between 781-

1000MHz at 3V/m, the instrument may not meet its stated

accuracy.

RoHS

Restrict to use of six substances within electrical

and electronic equipment (EEE), thereby contributing

to the protection of human health and the environment.

The device may not be disposed of with the trash.

It promotes the re-use recycling and other forms

of recovery of used materials and components, and

to improve the environmental performance of all

operators (manufacturers, traders and treatment

with the regulations in force in your country.

REACH

The device of used materials content no following

substances that list of proposed REACH substances

of very high concern.
