DESCRIPTION
Model 4010 utilizes a microprocessor SLEEP mode
to eliminate high frequency clock noise and their
associated harmonics. The microprocessor WAKES
momentarily to acknowledge front panel switch depressions
then goes to SLEEP immediately after processing and
executing the requested function. This allows the amplifiers
to operate with minimum self generated noise and provides
clean, clock free amplified signals.
The Model 4010 uses dual 12-bit DAC's, for each
channel, to autozero the input and output amplifiers for DC
input signals. Input signals with magnitudes of +/-10 Vdc can
be zeroed. Unzeroing the amplifier zeroes both autozero
DAC's. A unique output DAC trimming routine, allows
trimming the output zero to within +/-1 mVdc. Dual 12-bit
DAC's, for each channel, are also used to set amplifier gains
from 0.00 to 999.9 with +/-0.5% precision. Amplifier gains
can be changed "on the fly" without damage to the
instrument.
Each of the 3 amplifiers has a 150 kHz full power
and a 200 kHz small signal bandwidth and can drive 10mA
into a 1 K ohm load. A filter socket is provided, for each
amplifier, to filter broadband noise. A variety of optional 2-
pole high and low pass filter modules are available for
purchase under series 4198A and can be installed in these
sockets. See Table 1: Optional Filters for corner frequency
options.

The transducer excitation supplies are individually
adjustable for each channel from 0.00 to 12.00Vdc. Any
setting above 12.00Vdc will generate an excitation voltage of
12.10Vdc. The outputs are short circuit protected and can
supply up to 30mA each. Remote sense leads are provided
to eliminate errors caused by long cable lengths.
CE DECLARATION OF CONFORMITY -
Model 4010 has been CE tested for compliance to
EN61326-1:2013 for EMC emissions and immunity, and
EN61010-1:2010 for product safety.
OPERATION
To operate CH1, CH2, or CH3, perform the following
steps in the sequence shown.
Step 1: Set Vexc
a) Set the Gain/Vexc Thumbwheel
Switch (SW1) to desired Vexc.
Note: If the Thumbwheel Switch is set to a value >12.00,
Vexc will be 12.10 Vdc. For 0.00 < or = Thumbwheel Switch
Setting < or = 12.00, Vexc will be equal to the Thumbwheel
Switch Setting, when selected.
b) Depress the Channel Select Switch for CH1,
CH2 or CH3. The appropriate Channel Select
LED will illuminate and stay illuminated.
c) Depress the SET Vexc Switch (SW6). The
Channel Select LED will extinguish and Vexc
for the selected channel will be set to the
Thumbwheel Switch setting.
Example: Set Thumbwheel Switch to 009.75. Depress CH2
switch, then the SET Vexc Switch. Vexc for CH2 should be
9.75Vdc +/-1%.
Step 2: Set Amplifier Gain
a) Set the Gain/Vexc Thumbwheel
Switch (SW1) to desired amplifier gain.
Note: The amplifier gain can be set anywhere from 0.00 to
999.9.
b) Depress the Channel Select Switch for CH1,
CH2, or CH3. The appropriate Channel Select
LED will illuminate and stay illuminated.
c) Depress the SET GAIN Switch (SW5). The
Channel Select LED will extinguish and the
selected channel gain will be set to the
Thumbwheel Switch setting.
Example: Set the Gain/Vexc Thumbwheel Switch to 075.00.
Depress CH2 switch, then the SET GAIN switch. CH2 gain
will be set to 75.00.
Step 3: Zero the Amplifier
a) Verify the input to the appropriate channel is
the desired input to be zeroed.
Note: Any DC input signal, within the specified operating
range of the amplifier can be zeroed.
b) Depress the Channel Select Switch CH1, CH2,
or CH3. The appropriate Channel Select LED
will illuminate and stay illuminated.
c) Depress and release the ZERO Switch (SW4).
d) The amplifier, under microprocessor control,
will first zero the output of the input amplifier,
and then zero the output of the output amplifier.
The output will be 0.00 +/- 0.050 Vdc (typ).
Step 4: Trimming the Zero output
Note: Trimming allows the user to zero the output of the
selected channel to within ±1 mVDC. This trimmed value
may then be stored in non-volatile memory and reapplied
upon power turn on.
a) Perform Step 3: Zero the Amplifier
b) Depress and hold depressed, the Channel
Select Switch for CH1, CH2 or CH3. The
appropriate Channel Select LED will illuminate
and stay illuminated.
c) To increment the output zero by 1 count of the
output zero DAC, set the Gain/Vexc
Thumbwheel Switch (SW1) to “000.01 ".
To decrement the output zero by 1 count of the
output zero DAC, set the Gain/Vexc
Thumbwheel Switch (SW1) to “001.01 ".
d) Depress the ZERO switch. The output zero will
increment or decrement by 1 count of the
output zero DAC. Successive depressions of
the ZERO switch will continue to increment or
decrement the output zero.
Note: To increment the output zero by (x) counts of the
output zero DAC, set the Gain/Vexc Thumbwheel Switch
(SW1) to “000. 0 x” and depress the ZERO switch. To
decrement the output zero by (x) counts of the output zero
DAC, set the Gain/Vexc Thumbwheel Switch (SW1) to “001.
0 x” and depress the ZERO switch.
e) To save the trimmed zero value in non-volatile
memory, depress and hold depressed the Channel
Select switch again. The selected channel LED will
extinguish. The trimmed zero value will be stored in
non-volatile memory.
Note: If any other channel is selected before the selected
channel switch is depressed and held, the trimmed zero
value will not be saved and the previously stored zero value
will be used at power up.

Unzeroing the desired channel.
Note: Unzeroing the desired channel sets both autozero
DAC's to zero. This sets the amplifier to its natural zero
position. The output of the amplifier is offset by its own offset
voltage.
Step 1: Unzero the amplifier
a) Depress the Channel Select Switch for CH1, CH2
or CH3. The appropriate Channel Select LED will
illuminate and stay illuminated.
b) Depress and hold the ZERO Switch (SW4)
until the appropriate Channel Select LED
extinguishes. The selected Channel amplifier
is unzeroed.
Applying an internal shunt calibration resistor (Rsh) to
the selected channel bridge network.
Note: Internal solder jumpers allow for a positive or negative
responding Rsh. The shunt cal resistors are removable and
may be installed by the user. Reference Location of Filter
Modules and Rsh Resistor in the figure below
WARNING: Turn Input Power Switch OFF before removing
power cable from the instrument. Remove power cable from
the instrument before disassembling any part of the
instrument.
a) Simply depress and hold the Rsh Switch for
the desired channel amplifier. The shunt cal
resistor is applied to the appropriate
transducer bridge circuit terminals for the duration
that the Rsh Switch is depressed.
