    Warranty and Service ...................... 14 Each Stimulus Isolator is delivered complete with: Battery Charger NOTE This instrument is not intended for clinical measurements using human subjects. A-M Systems does not assume responsibility for injury or damage due to the misuse of this instrument.
  • Page 4: General Description

    An internal battery tester is provided. A charger is supplied, and an oven-night charge cycle is all that is required to ready the 2200 for another day’s use. It is easy to swap a freshly charged pair of batteries if extended use is necessary.

    Model 2200 output. Some kinds of connectors (e.g. BNC connectors) have exposed metal parts which may float at dangerous potentials unless externally connected to safety ground. For greatest safety, turn the Model 2200 off before handling connections to the output.
  • Page 6 For users requiring the lowest possible offset voltage or current, it maybe necessary to readjust the Offset. Use the small insulated screwdriver (supplied with the Model 2200) to zero the output while the input voltage is set to zero. It is best to do this with the Range switch set to the desired position.
  • Page 7 Figure 1. Bottom view of case: screw locations If for some reason it is necessary to store the 2200 for more than a few months, it is recommended that the unit be kept at a low temperature(5-10°C). Before storing for longer than a year, it is advisable to remove the batteries from the unit;...
  • Page 8 Do not connect the Battery/Test signal permanently low: this would reduce battery charge life, and prevent real output errors from being detected. Do not connect anything to pin 5 of DB-9 connector without consulting A-M Systems, or its representative. A-M Systems...

    Power off, disconnect the 1kW resistor, and turn the Power back on. The output waveform should be much larger (flattening against the power supply rails), and the error LED should light up as the 2200 fails to drive up to 6500mA into the high impedance of the oscilloscope input/load.

    Combing Two 2200’s For Increased Output If you require up to twice the maximum output voltage, connect two 2200 units in a series. If you require up to twice the maximum current of a single 2200, connect the 2200’s in parallel.

  • Page 13: Theory Of Operation

    The batteries used in the 2200 vary more from unit to unit than from fullly-charged to nearly-discharged, making it impractical to measure the charge state. It is recommended that you, the user, keep track of battery usage to ensure that the battery does not become exhausted at a critical time.
