Operating instructions of SZG-20B SZG-441C Tachometer

1. The key at the top is the measuring switch. Press the measuring switch to measure. At this time, the tachometer is in the measuring speed state, and the unit is r/min.

2. The next key is the deposit key. Press this key to call up the post measurement of deposit.

3. There are various speed measuring heads in the accessories, which are applicable to various speed measuring conditions. The conical speed measuring head is used for speed measurement, and the unit of displayed value is r/min; The disc speed measuring head is used for linear speed measurement, and the unit of displayed value is 10cm/min. The long rod is used to lengthen the speed measuring head and extend the detection depth of the speed measuring head.
