Model DTX2

INSTRUCTION MANUAL

INTRODUCTION

Model DTX2 is a highly sophisitcated, cap torque tester which offers
programmable high/low setpoints for go/no go testing. Store up to
1,000 values into memory, which can be transmitted using Digimatic
or RS-232 formats. Use the Real Time mode to display torque tran­sients, or the Peak mode to capture the peak torque achieved during
a test. Select measuring units between lb-in, kg-cm and N-cm.

PRECAUTIONS

DTX2 Cap Torque Tester is a sensitive instrument. The load cell
can be damaged regardless of whether the unit is ON or OFF.

Follow these precautions to keep your DTX2 from being damaged.

1. Do not exceed unit’s capacity regardless if power is on or off.

2. Only use the Imada AC adapter/charger, other brands may cause
serious damage.

3. Accuracy may be affected if unit is exposed to high humidity,
dust or extreme shock.

4. Do not disassemble unit. Disassembly voids warranty.

5. Recommended re-calibration cycle is one (1) year.

6. When operating or moving do not lift or twist the DTX2 table
or carry by holding the knob or table.

7. Before shipping, remove the DTX2 table from the base and
pack both items together.

PREPARATION

The sample table (C) must be assembled with the main unit.

1. Connect AC adapter/charger (AD120) to the tester, then plug
into 115 VAC outlet (AD230 AC adapter/charger for 230VAC).
Tester can also use inter­nal Ni-MH batteries
without plugging into
AC power. Turn on the
tester and check that the
display is at zero and
overload indicator is
not flashing.

CAUTION:

Do not put any foreign
object in the opening.
Do not put excess force
or weight on sample
table (C).

PREPARATION (continued)

2. Hold sample table (C) upright with clamp handle (A) on right.

3. Slowly insert shaft on bottom of sample table (C) into top circu­lar opening of main unit (make sure key and key way line up).
CAUTION do not apply excessive torque when assembling. If
unit is overloaded the overload indicator will flash (the tester
can be overloaded whether ON or OFF).

4. Choose hole locations for holding pegs based on the size of
the container being tested. Make sure the hex portion of the
pegs fits into the groove to prevent peg rotation.

NOTE:

Make sure hex portion of the
peg fits into the groove to pre­vent peg rotation.

Tare

Clamp container firmly to the sample table (C) by tightening the

clamp handle (A). If necessary, press to tare before the test.

Pressing also clears the peak reading.

Grip the sample lid and rotate to open (CCW) or close (CW). The

display will indicate the torque value with CCW or CW icons.

RECHARGING NI-MH BATTERY

1. To maximize the life of the battery, power is automatically shut
off after 10 minutes of non-use or user-defined interval.
Automatic shut off is bypassed during USB output or when
used with the AC adapter/charger.

2. Battery icon will flash when the tester needs to be
recharged.

Clamp container, then twist
sample lid by hand to
measure torque.

If High and Low setpoints have been programmed (see page 5),
for example, 5 lbf-in is set as Low and 10 lbf-in as High, the
ORANGE LED light for measurements less than 5 lbf-in (Low set­point). GREEN lights between 5–10 lbf-in and RED lights over 10
lbf-in (High setpoint). Setpoint output is available through the
Communications port (see page 7).

After measuring, press the button to transmit data to:

RS-232 models: RS-232C or Digimatic devices

3. Push to turn off power. Only use the IMADA AC adapter/
charger provided, AD120 for 115VAC, AD230 for 230VAC. Plug
into the correct AC output. It takes 10 hours to charge fully.

4. When the tester is turned off, make sure the AC adapter/charger
is disconnected to avoid overcharging.
