3.1 /TEST Key

1. Press the button to turn on the instrument.
   Note: The instrument will automatically shut down if there is no key operation for about 15 seconds by default.

2. Press and hold, the instrument starts to measure.

3. After the measurement is released, the instrument will lock the measured value, and the value will not change after being locked.

3,2 /UNIT Key

1. Short press to switch the unit RPM{revolution/minute), Hz(Hertz), m/min({meter/minute) and ft/min(feet per minute).
2. Long press to turn on or off the screen backlight.

3.3 MEM Key

1. View the currently measured lock value (HOLD), maximum value (MAX) and minimum value (MIN).
2. View the locked value (MEM HOLD), maximum value (MEM MAX) and minimum value (MEM MIN) of the last measurement before the instrument is turned off.

Measurement Procedure

4.1 Photoelectric Soeed Measurement (Only applicable to some models)

1. Paste a reflective mark on the object to be measured.
2. After turned on, short press ****/UNIT” key to choose “P-RPM” (If the contact accessories have been installed, please remove the accessories and accessory connectors).
3. Press and hold the /TEST” key, at the same time, make the red laser and the reflection mark in a straight line; after the data is stable, release the /TEST™ key, the instrument locks the current data.
4. Press the “MEM” key to view the lock data, maximum data and minimum data.

Note: a. When the rotation speed is low, a few more reflective marks can be evenly affixed on the rotating surface. Note that the non-reflective area is larger than the reflective area (The final rotation speed value is equal to the value displayed by the instrument divided by the number of reflective marks).
b. If the rotating surface is obviously reflective, please apply black paint or black tape before attaching the reflective marker.
4,2 Light Source Flicker Frequency (Only applicable to some models)

1. After turning on the machine, short press the /UNIT” key to select “P-Hz” (If contact accessories have been installed, please remove the accessories and their connectors).
2. Align the measuring window of the instrument with the light source to be measured.
3. Press and hold the /TEST” key, and release the key after the value is Stable, the instrument locks the current cata.
4. Press the “MEM” key to view the locked data, maximum data and minimum data.

4,3 Contact Soeed Measurement (Only applicable to some models)

1. Install suitable contact speed accessories.
2. After starting up, short press the /UNIT” key to select “C-RPM”.
3. Clase the accessory to the object to be measured and make it rotate synchronously with the object to be measured.
4. Press and hold the /TEST” key, and release the key after the value is Stable, the instrument will lock the current cata.
5. Press the “MEM” key to view the locked data, maximum data and minimum data.

4.4 Contact Line Speed Measurement (Only applicable to some models)

1. Install the contact line soeed accessories.
2. After starting up, short press the /UNIT” key to select “C-m/min” or “C-ft/min”.
3. Close the accessory to the object to be measured and make it rotate synchronously with the object to be measured.
4. Press and hold the /TEST” key, and release the key after the value is Stable, the instrument will lock the current value.
5. Press the “MEM” key to view the locked value, maximum value and minimum value.
