Belt tension meter set (MB992080)

1. Connect special tool microphone assembly 

(MB992082) to special tool belt tension meter 
(MB992081) of special tool belt tension meter set 
(MB992080).

2. Press the "POWER" button to turn on the power 

supply.

3. Press the numeral key of "1" and check that 

"No.1" appears on the upper left of the display.
NOTE: This operation is to temporarily set the 
preset data such as the belt specifications, 
because if the measurement is taken without input 
of the belt specifications, conversion to tension 
value (N) cannot be made, resulting in judgement 
of error.

4. Press "Hz" button twice to change the display to 

the frequency display (Hz).
