6.3 User-selected cable type
•
You can store up to 8 of your own cable types.
•
The length can then be measured on any conductive cable.
6.4 Save the resistance in a cable type of your choice
Note:
Prepare a 4-100m [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 of wire when you want. Make sure the
sample wire to be measured is not energized or live.
Accurately measure the length of the reference cable with tape measure or otherwise.
In the instrument will then measure the resistance in the reference cable and store this
information.
For best results, the instrument and reference cable should have roughly the same ambient
temperature, which will typically take about 30 minutes.
Insulate and clean the wire ends of the reference cable to achieve good contact.
If necessary, use abrasive paper to remove oxide layer on each end if necessary.
The reference cable must not be live.
1. Calibrate the instrument as described in
6.1 calibration procedure
2. Set
the rotary switch [10]
to one of the custom positions (1 to 8).
The selected position is displayed in the display. For example, if position 3
the display shows
, if the position is already in use the display
shows
. The display shows "
no
" when the "space" is free.
3. Press the
FT/M
key and select the unit Feet or Meter.
4. Connect the two alligator clips to the ends of the reference cable
5. Press the
CAL
key to go to the
cable length setting.
In this mode, the display alternately
shows and additionally
flashes
and
.
6. The display shows minimum length of 4m, hold the
up arrow key until the value
corresponds to the length of the reference cable, use
the down arrow key to lower the
value on the display in step of 0.1 until the display accurately shows the length of the
reference cable.
7. Now press the
MEM
key. If the display shows
and returns to the
measurement mode, the setting is completed correctly.
If the display shows
and
the setting is not done
correctly, check the connections.
6.5 Measure the length of custom cable type
1. Calibrates the instrument as described in
6.1 Calibration procedure
.
2. Insulate the cable to be tested at both ends and make sure that a good contact can be
made.
3. With
the rotary switch [10],
select the position (1-8) that suits the selected type of cable.
4. Press the
FT/M
key to choose whether to view the result in
Feet
or In
Meters
5. Connect alligator clips at both end of the cable.
6. The display now shows the total length of the custom cable.
