String Length Meter Operation
To enable the String Length Meter (SLM) function, press
the String Length function key on the keypad. When the
String Length button is pressed, one of the Red LED
indicators below “M” or “FT” will light up to indicate that
the SLM function is enabled. Pressing the String Length
button will toggle between “M” and “FT” to set the
measurement units for either Meters (“M”) or Feet (“FT”).
Measurements are displayed in 0.1 increments.
To measure out a length of string from a reel (sets can
also be measured) insert one end of the string through
the string guide grommet (from the backside). While
lifting the clamp pad, insert the string through the
entrance hole of the face plate until it appears at the exit
hole and release the clamp pad. (The clamp pads will
prevent debris from entering the SLM.)
When the end of the string appears out of the exit hole,
press the “C” button on the keypad to “Zero” the SLM,
and the length of string measured will be measured from
the point on the string located at the edge of the exit
hole. Pull the end of the string in a slow steady fashion
and the SLM will begin measuring the length of string
pulled and indicate the measurement on the LED dis-
play. When the desired length of string is measured, cut
the string at the exit hole.
NOTE :
When reaching the end of a length of string,
pull the string through very slowly to avoid inaccu-
rate string measurement.
The string length meter was
designed to measure strings between 1.10 mm (18 ga)
and 1.45 mm (15 ga) at an accuracy of +/- 0.3% of the
indicated value and +/- 2 inches (50 mm) absolute.
When measuring strings smaller than 1.10 mm (such
as badminton strings) the error will be -2.5% of the
indicated value (up to 6” short in 40 ft) and +/- 2 inches (50 mm) absolute.
