Operation
• Switch instrument on (10)
• Select the appropriate method with the „modus“ button and
confirm with „enter“
• Clean the balls of the pendulum with acetone or alcohol
• Place the sample on the lifting table (6)
• Raise the lifting table (6) with the handle (7)
• Move the pendulum with the displacement arm (8) to the starting
position (6° König/12° Persoz) and hold it by pressing
the wire release (3)
• Press the „start/stop“ button, until an * appears on the display
and the red LED „busy“ lights up
• Release the pendulum to start measurement
ENGLISH
• Avoid vibration and air draft during the measurement
How to measure the Pendulum Hardness?
Depending upon the method, the number of oscillations or the
oscillation time is the output.
Pendulum Hardness according to „König“: number of oscillation
1 Oscillation = 1.4 seconds
Pendulum Hardness according to „Persoz“: oscillation time in sec.
1 Oscillation = 1 second
Control of measurement accuracy
For periodical control of the instrument, it is recommended to measure
the included glass plate once a week.
The following values need to be reached:
Pendulum Hardness according to „ König“: 179 ± 3 osc.
Pendulum Hardness according to „ Persoz“: 430 ± 10 sec.
