Tonearm scale  

Revox delivers the T700 with a digital tonearm scale in the accessory box for precise determination of the tracking force. This 
allows you to set the tracking force recommended by the manufacturer of the cartridge to an accuracy of 0.01 g. A test weight 
of 5.0 g is included in the accessories box for checking the measurement accuracy.  
The scale plate is very sensitive and therefore has a protective cover that  can be pulled off to the right. The protective cover 
should be used when the balance is not in use.  
 
The tonearm scale has 3 buttons with the following functions:  

 

Measurement 

Switching between different units of measurement. 
 

 

Power 

Switches the tonearm scale on and off. There is an automatic switch-off function after approx. 120 seconds. 
 

 

Tare 

This key can be used to perform a zero adjustment. To do this, the scales must be placed on a flat, horizontal surface. If the tare 
key is pressed and held, the currently measured weight is classified as a value of 

0

. After resetting the supplied test weight, the 

tonearm scale should show a value of 4.98 - 5.02 g.

Calibration  

A calibration should only be carried out if there are problems with determining the tracking force or the enclosed test weight of 
5.00 g is not displayed correctly.   

Procedure

:   Switch  on  the  scale  with  the  power  button 

  and  wait  until  the  scale  shows  0.00  g.  Now  press  and  hold  the 

power button 

 until the display shows 

- 0 -

. Wait until the displays 

flash

 the required test weight of 

5.00 g

. Now 

place  the  enclosed  5  g  test  weight  on  the  scale.  The  display  now  shows  5.00  g 

continuously

  and  ends  the 

calibration  process  with  the  display 

PASS

.  If  you  now  remove  the  test  weight,  0.00g  appears.  The  calibration  is 

complete.
