Sec. 2. CHARGING INSTRUMENT BATTERIES.
1. Connect power supply cable to instrument.
2. Plug the power supply into a 100 – 240 VAC outlet.
3. Fully charge battery prior to first use (approximately eight hours).
4. Battery pack assembly cannot be overcharged, however instrument will
remain on while plugged into power supply.
5. Fully charged battery assemblies will operate approximately six hours
+/- 20% depending upon usage and backlighting intensity.
6. Battery charge level is indicated in the upper, right-hand corner of
display.
Sec. 3. OPERATION:
QUICK START
.
1.
TURN UNIT ON
by pressing
ON
button. Display shows:
Tension
(LBS,
Newtons, or Kilograms),
Cable
size selected and battery charge level.
2.
MEMORY FUNCTION.
Depress the
MEMORY
button to store and
display up to five separate tension readings, plus the average (
AVG
) of
these stored values.
3.
MOVE BETWEEN SCREENS
by pressing either the
↑
or
↓
arrows. To
make, or enter a selection, depress the
ENTER
key. To exit a setting,
depress the
ESCAPE
key.
4.
ZERO THE INSTRUMENT
before taking readings by holding the
instrument in the attitude in which it will be used, and with no load
applied press the button marked
ZERO
.
5.
READING OF TENSION.
Variations in materials and sizes affect
tension readings. It is essential to select the correct material and size
from the calibration menu before use , or values may be incorrect.
6.
SELECT MATERIAL.
From the Main Display (first screen seen when
unit is turned on) use the
↑
or
↓
keys until
SELECT MATERIAL
is
displayed. Press
ENTER
. Next toggle through the various selections
using the
↑
or
↓
arrows until correct cable size is highlighted, and press
ENTER
to make your selection.
If your specific material is not listed,
follow the calibration instructions included at the end of these
instructions, or send a sample and the instrument to Tensitron for a
custom calibration.
7.
SELECTING TENSION UNITS IN lb, kg or daN.
Press the
↑
or
↓
keys
until
TENSION UNITS
is displayed. Press
ENTER
. Next, select:
LBS
,
Kilograms
or
Decanewtons
and
ENTER
selection.
8.
ENGAGE INSTRUMENT TO TENSIONED MATERIAL.
For best
accuracy hold the instrument in the attitude the measurement will be
taken in and press
ZERO
. Push “closure bar” away from the instrument
handle to raise the outer cable guides. Engage the tensioned material
by routing the cable so that it falls under the outer cable guides and over
the center, contact point. Squeeze the “closure bar” shut until it locks
into position beside the handle, and note the tension reading. (See
photo on Page 14.)
Page 2 ACX-Series Operating Instructions
Verify the tension value. For example, if your suspended
weight is 41.0 lb your instrument should also indicate 41.0 lb
+/- 5.0 lb once properly engaged to the cable. This procedure
confirms the instrument’s accuracy and it is now ready for use.
Note:
Full-scale accuracy is +/- 2% for all menu selectable
calibrations. Accuracy for custom calibrations is material spe-
cific.
For an instrument with a full-scale range of 250 lb this trans-
lates into +/- 5.0 lb, and for an instrument with a full-scale
range of 500 lb, accuracy is +/- 10.0 lb.
* Should you have additional questions, please contact
Tensitron to speak with an applications engineer.
