| My
gauge is not charging. What could it be?
Reset
battery life to 190 hrs. Ensure charger is good. Check charger jack
to see if it is loose/broken. Possible bad battery pack.

| My
gauge displays tube error. What's the problem?
Take the gauge to a clean, dry environment and remove the control
panel or "scaler". Check for loose hardware inside the gauge
that could short the high voltage. Check for moisture inside the gauge
and, if moisture is present, remove the scaler and dry overnight with
a fan.

| Why
does my gauge fail the standard count?
Ensure that the gauge is positioned
properly. Make sure that those std. counts stored are appropriate
by comparing to the factory std. counts.

| When
I try to get my density, I get nothing but +'s. Why?
Obtain the gauge's most recent calibration printout and check
that the calibration constants in the memory match those on the printout.
Also, verify that the depth strip is functioning correctly. Check for
correct standard counts.

| Why
are my gauge readings off?
Ensure you have a good standard count. Verify you are at the
correct depth. Check to make sure no offsets are enabled.

| |
| Why
is my gauge hard to index?
Magnalube is the recommended lubricant. Place a small amount on the
source rod and exercise the rode up and down. Check the bottom of the
gauge to make sure dirt has not accumulated in the sliding block or
base plate area.

| Why
does my gauge indicate safe position when it is in BS?
You need to calibrate the depth
strip. If this doesn't fix the problem, your gauge may need servicing.

| What
is the prescale factor for my Troxler gauge?
In order to scale the count values to a reasonable number of digits,
Troxler devices use prescale factors when performing measurements, standard
counts and any other diagnostics count. In other words, the count
that a gauge displays is the total number of ionization events measured
by the gauge divided by the appropriate prescale factor.
The prescale factor is typically not needed by the gauge operator.
However, the ASTM standards D 6938 and D 2950 give a formula, to check
the stability of the standard counts, which requires the use of the
prescale factor. The prescale factors are listed below:
For Troxler Models 3401, 3411,
3430, 3440
and 4300
devices, the prescale is 64 for a 4 minute (slow) count and 16 for a
1 minute (norm) count. Standard counts are typically taken as
a 4 minute count, therefore the prescale of 64 is used.
For Troxler Models 3450
and 4640
devices the prescale is 32 for a 4 minute (slow) count and 8 for a 1
minute (norm) count. Standard counts are typically taken as a
4 minute count, therefore the prescale of 64 is used.

| My
gauge is locked up and there is no keypad response.
Press and hold the OFF button for 15-30 seconds until the gauge turns
off. If it does not turn off, remove the scaler and unplug the ribbon
cable from the baseboard. Plug the cable back in and turn the gauge
on allowing it to go through its 5 minute self-test.

| My
3411 displays "ERROR 30". What is wrong?
Take a new standard count. (Note: A standard count must be taken each
time a 3411 is turned off. It does not store standard counts.) Ensure
depth switch is at the correct depth.

| What
could cause the voids to be high in compacted specimens on a 4140?
Possibly the brake is slipping and thereby not allowing the angle to
be fully set on. Tighten the brake cable until the brake ring doesn't
slip during angle on operation.

| What
causes the mold to get stuck in a 4141? How is the mold removed?
A zero angle screw stuck in the down position. Power off machine and
remove the top electronic box. Unscrew the three zero angle screws (pulley
atop each). Power on machine and escape to Idle screen. Press Setup
then item 6 (manual). Select item 5 (unlatch mold). Select item 4 (lower
ram).

| What
causes the 4141 to fail pressure calibration?
The most likely cause is a loose one inch nut on the jack. Remove the
front panel and lift the jack shaft by hand (place height standard under
head inside chamber to keep it held up). Remove the one inch nut atop
the jack screw and turn the shaft counterclockwise to screw the anti-rotation
bar firmly down. Clean the nut and apply blue loctite to the treads
before tightening it back on the jack shaft.

What causes a loud
noise combined with the ram stopping on a 4140?
This is most likely caused by a failure on the CPI board. Please contact
technical
support for assistance.

| What
causes garbled display data on the 4140 console display?
If the printer power cord is plugged into an outlet other than the aux
outlet on the rear of the compactor a power glitch can cause this. Power
down both printer and compactor and plug printer power cord into compactor.
Power on compactor and then printer.

| What
causes the angle to not be displayed during gyration on a 4141?
Either a defective angle sensor or the sensor has become unplugged.

| What
can cause the turn table on a 4140 to not turn at all?
A defective DCMI board or failed D.C. Motor Controller. Please contact
technical
support for assistance.

| What
causes the 4155 to continue to heat well past the set point?
A failed solid state relay (the middle one on the power cord panel).
Please contact technical
support for assistance.

| What
causes the 4155 to signal end of burn after only twenty some minutes?
The constants may have been corrupted by a power glitch. Print the constants,
reset the machine and chamber, re-calibrate the Weight Window, recalibrate
the scale, and re-enter the temperature constants.

| What
causes the 4155 temperature display to show around 1480 and the chamber
to not heat?
A broken chamber thermocouple. Please contact technical
support for assistance. |
