2 - Installation
Before installing your 6200, you should become familiar
with the front and rear panels, as outlined in Chapter 1Introduction.
Make sure the 6200 is earth grounded
before starting!
CHECKING YOUR 6200
Do not overload or stall the motor.
Prolonged overload can cause the motor
to overheat.
NOTE:
SETTING UNIT FOR LINE VOLTAGE
The 6200 will operate with either of the following power
sources:
• 120V 50/60 Hz
• 240V 50/60 Hz
1. Find the line cord receptacle on rear panel. The
line cord is a detachable NEMA Standard 3 wire.
2. Make sure the selector matches the power source
(numbers should match the line voltage).
If not:
• Locate the power entry module.
• Remove the line cord.
• Insert a screwdriver into the slot and open the
cover.
• Slide the voltage selector so the desired line
voltage appears in the window.
• Install the appropriate fuses for that voltage.
Figure 6.
Cover for Voltage Selector, Fuses
To make sure that the 6200 is
operational, a Magtrol
dynamometer with a test motor
installed must be connected to
the 6200. It is not required that
the 6200 be connected to a
computer.
1. Connect the 6200 to the dynamometer using the
following cables:
• 14-pin signal cable
• 2-pin brake power cable
2. Turn on 6200 power.
Desired results:
• The display panel will show all segments of
the VFD (series of rectangles), indicating that
the 6200 is executing a self-test routine.
• Message "MAGTROL 6200" appears.
• Normal display panel appears.
3. Press the UNITS DISPLAY button and set current
output to 0% with Decrease/Increase Dial.
4. Start the test motor.

7. Turn the Decrease/Increase Dial clockwise.
Desired results:
• The torque reading will increase.
As brake power is applied, load is applied to
the motor. The applied torque increases as the
Decrease/Increase Dial is turned clockwise. For
most motors, loading is indicated by motor
speed reduction.
7

GPIB (IEEE-488) Interface
ABOUT THE GPIB INTERFACE
(General Purpose Interface Bus)
D1
1 13
D5
Magtrol instruments use the GPIB (IEEE-488 Standard)
for computer-to-instrument interfacing because:
• The GPIB parallel interface is faster than serial
interfaces.
• The GPIB enables testers to access up to 15
instruments on one port. Because typical motor
testing requires that at least five separate
parameters must be synchronized, a system of
easy, fast access to more than one instrument
is essential.
• The GPIB has rigid data formatting and
hardware standards. These standards help to
ensure that all functions will work properly
when the hardware and software are installed.

5 - Calibration
CLOSED-BOX CALIBRATION
The 6200 features closed-box calibration. The advantage
of closed-box calibration is that the user does not have
to disassemble the case or make mechanical
adjustments. However, the calibration of the Accessory
Torque Output must be done internally with Offset and
Gain trim pots.
The Torque readout and Auxiliary Input can be
calibrated using external reference sources. Correction
factors for Offset and Gain are stored in nonvolatile
memory. They remain in effect until the user or the
calibration house updates them.
The front panel displays the actual values for the ZERO
and GAIN correction factors. Record these values
before calibration. In the unlikely event of a Controller/
Readout failure, it can re-initialized by pressing and
holding the STORE and RECALL buttons while turning
the power on. All internal memory and setups will be
lost. After re-initializing, reprogram the GAIN and
ZERO values into memory.
CALIBRATION SCHEDULE
INITIAL CALIBRATION PROCEDURE

The 6200 can also be calibrated by using a certified
dynamometer, calibration beam, and weight instead of
an external voltage reference.
NOTE:
Magtrol suggests you do NOT
use this method. By using the
alternate calibration procedure,
you are calibrating the 6200 to a
specific dynamometer, not to a
reference standard. If you
connect the 6200 to a different
dynamometer, the resulting
torque reading may be incorrect.
1. Connect the chosen dynamometer to the 6200 using
the 14-pin signal cable and the 2-pin brake cable.
2. Attach the calibration beam to the dynamometer
shaft.
3. Enter the calibration mode.
4. Press the BRAKE ON/OFF button ON to apply full
loading to the dynamometer.
5. Hang the weight on the calibration beam pin and
level the beam.

8. Remove the weight for ZERO adjustment.
9. Press the UNITS DISPLAY button.
10. Adjust the Increase/Decrease Dial until the display
indicates 0 mVDC.
NOTE:
The mV output of the
dynamometer will be equivalent
to the Weight times Distance on
the calibration beam,
disregarding any decimal point.
Example:
Magtrol’s HD-400-6 Dynamometer has a fullscale torque of 40.0 oz.in. The distance from
the center of the dynamometer shaft to the pin
on the calibration beam is 5 inches. Placing an
8 oz. weight on the pin will produce a torque of
40.0 oz.in. The mV output of the dynamometer
will be equivalent to 8 oz. multiplied by 5
inches, yielding an output signal of 400 mV.
11. Repeat steps 5 through 10.
12. After completing calibration:
• Press the BRAKE ON/OFF button OFF to
remove loading from the dynamometer.
13. Remove the calibration beam from the
dynamometer shaft.
14. Proceed with your desired motor testing.
