6.3. User Select Mode
• The use select mode allows user to save the resistance parameter of a
user wire for length measurements of the wires of the same kind(Same
gauge and same conductor material).
• In addition, it enables user to accurately measure the length of standard
gauge wires.
• In this mode, user can measure the length of any metal wires (including
copper or aluminum wires).
Note: The sample length of user wires must be between 4m and 100m in
METER mode or between 13.1ft and 320ft in FEET mode.
6.4. How to save the resistance of a user wire
Note: Prepare a 4-100m(or 13. 1ft-320ft in FEET MODE) Sample length of
the wire to be programed into the meter
so that the meter can correctly measure the resistance of this sample wire
and store it in lengths of the same kind
wire when you want. Make sure the sample wire to be measured is not
energized or live.
1. Set the rotary switch from the OFF to Ω Position.
2. Calibrate the meter as described in "Calibration Procedure".
3. For best results, allow the meter and the sample wire to be measured to
attain the same ambient temperature.
4. Remove the insulation at both ends of the cable under test.
Note: Make sure that the two conductors of the cable under test are clean
and fully exposed, and that the insulation must be removed to make it
easier for the test rod to fully clamp the cable. If desired, use an abrasive
paper to clean the exposed wire head.
5. The rotary knob selects the user-defined mode gear, and there are 1 to
8 (8) user-defined mode gears on the meter, the selected gear is
displayed in the upper left corner of the screen.
6. For example, when the user selects the knob, "
on the screen if the selected gear already has a cable parameter, the
screen will display "OL".
7. Press the FT/M Buttons to select feet or meters.
8. Press the CAL Button, The meter enters sample wire length setting
mode; in this mode, the display alternately show "
"
" among them "MEM" and "TCAL" flash twice each time.
