Product Manual

Power
The gauge may be powered by the internal 9V battery, or by the included AC
adapter. The need for the battery replacement is indicated by a 3-step sequence:
1 - a steady LO BAT appears on the display indicating the last 10% of the battery
life, 2 - LO BAT begins to flash indicating the need for an immediate battery
replacement, 3 - the entire display except LO BAT flashes for several seconds
and then the instrument shuts off.
Calibration
To properly calibrate this instrument, application of an exact load appropriate for
your model will be required It must be in pounds as indicated by the model num-
ber. For example, the 12-0340 requires a 50 lb calibration weight regardless of
displayed units. While holding PEAK, turn the gauge on. Press PEAK repeatedly
until 'CAL' appears on the display and press POWER three times to select the cal-
ibration mode. At the 'null' prompt press ZERO. At the 'SPAn' prompt apply your
test weight and press POWER. The display will show "uuuu" or "nnnn" if the test
weight is insufficient or excessive accordingly. If this happens, the only way to ter-
minate the calibration mode is by momentarily disconnecting the battery or con-
necting the AC adapter without plugging it into a wall outlet. This will stop the cal-
ibration procedure without making any changes to the previous calibration data.
A successful calibration is indicated by 'donE' on the display. Press POWER to
save the changes and resume normal operation.

Controls
The force gauges have three keys for controlling all functions of the instrument.
POWER Turns the instrument on and off. It is also used to select an option in the
setup mode. PEAK Used to select Tension Peak, Compression Peak or normal
(real time) display mode. The actual peak readings are always captured and can
be displayed at any time. ZERO Zeros any tare value (up to the full capacity of
the gauge) and clears the peak readings stored in memory.
Display
The display consists of a 4 1/2-digit section and several indicators. Their functions
are listed below.
LO BAT Low battery voltage indicator
C Compressive force indicator
T Tensile force indicator
C PEAK Peak compressive force indicator
T PEAK Peak tensile force indicator
LB, KG, N, G Units of measurement (model dependent)
- - - - (dashes) Overload (>110% of range)
Operation
The default mode of operation is the normal (real time) mode. If the peak read-
ings are to be observed as they occur, then the mode of operation can be
changed by pressing PEAK until the desired mode (C PEAK or T PEAK) appears
on the display. Please note that this action affects only the display. The actual ten-
sile and compressive peak readings are captured automatically and can be
cleared from the memory by either pressing ZERO or shutting off the gauge. The
gauge is equipped with an automatic shutdown feature which will shut it off after
a selected period of inactivity (readings do not change by more than ±10 counts
and no keys are pressed). The entire display will flash for 5-7 seconds as a warn-
ing of the imminent shutdown. If during this time any condition indicating activity
occurs, the internal timer will be reset and the instrument will continue its opera-
tion. To change the default setting of 30 minutes, hold PEAK while turning on the
gauge. Press PEAK repeatedly until 'AOFF' appears. Press POWER to select this
function. The current setting will flash on the display. Use the PEAK key to scroll
through the displayed choices and POWER to select. Press POWER again at the
'donE' prompt in order to save the setting.
Select Displayed Measurement Units (lb, kg, N)
The displayed unit of measurement and the default mode of operation (peak or
normal) can be changed by entering the setup mode. To enter setup mode hold
PEAK while the unit is off, and while holding PEAK press POWER. Once in setup
mode, press PEAK and ‘init’ will appear. Press POWER at the 'init' prompt and
toggle through pounds, kilograms and newtons by repeatedly pressing the PEAK
button. When the appropriate measurement unit has been selected, save the
change by pressing POWER. Press Power twice more to exit setup mode. NOTE:
if you decide not to change the unit of measurement after entering setup mode,
you must toggle through all three units (lb, kg, N) in order to exit setup mode.
