Zeroing the Gauge

Changing the unit of
measurement

Max (Peak) Readings

"Max" mode

A load indicator bar alerts the operator to how much load
has been applied to the transducer.  As the load approaches
the maximum rating of the transducer, the indicator bar
changes appearance when above approx. 80% of the rated
capacity. This warns the operator that steps should be taken
to prevent excessive load being applied.

For tensile forces the indicator bar is solid then dotted.  For
compressive forces the indicator bar is dotted then solid – see
fig. 3b & 3c

During the operation of the gauge it is often necessary to
zero the display – e.g. when you wish to tare out the weight
of a grip, so it does not become part of the measured
reading.  Press and release the 

ZERO

key.  The display will

blink momentarily as the zero operation is carried out.

You can choose from the following units of measurement
depending on the capacity of your gauge: millinewtons,
kilonewtons, newtons, gram-force, kilogram-force, ounce-force
or pound-force.

To change the display units press and release the 

UNITS

key.

Each successive key press will select the next available units
until the gauge returns to its original setting.  The BFG-HS
automatically converts readings as new units of measure are
selected.

The gauge detects and stores maximum (peak) force in both
compressive and tensile directions.

Press the 

MAX

key.  The display will show the word MAX

together with the highest tensile     force and the highest
compressive     force detected during the test.  The current
load being applied to the transducer is also displayed.-
