Belt mass constants are provided on pages 11, 12, and 13 of this
manual. Capacity available for input is from 000.1 to 999.9 grams/meter.
Press the “MASS” key and enter numbers on the keypad. Make sure the
decimal is placed correctly in the display panel. If your entry is incorrect,
press “MASS” again and the cursor returns to the original position.Enter

Capacity available for input is from 000.1 to 999.9 millimeters or number
of ribs or strands.
For a Synchronous belt, enter the belt width in millimeters.
For an Industrial V-belt, enter the number of strands being measured.
For a PolyFlex
®
JB
®
belt, enter the number of strands being measured.
For a Micro-V
®
belt, enter the total number of ribs.
For a 21 mm wide Poly Chain
®
belt, enter “021.0”;
For a 1” wide PowerGrip
®
timing belt, enter “025.4”;
For a single strand Industrial V-belt, enter “001.0”.
When using the Sonic Tension Meter on drives with multiple single or
PowerBand
®
belts, be sure to use the appropriate mass constant and
enter the correct number of belt strands being measured. There is no
need to multiply the mass constant by the number of ribs/strands, as the
Sonic Tension Meter will calculate the correct total belt mass.
Example:
For a V-belt drive using four individual 3V belts enter “1” for the belt
width (“Width” key). The Sonic Tension Meter will display the static
belt tension per individual belt. When measuring the belt tension in the
V-belt drive, make sure the V-belts do not interfere with each other while
vibrating.
If the same drive used a 4-strand 3V PowerBand
®
belt instead of single
belts enter “4” for the belt width (“Width” key). The total belt tension for
all four belts is measured as the entire belt vibrates. The Sonic Tension
Meter will display the total static belt tension for the PowerBand
®
belt (for
all strands within belt).
