FISCHER MD-1a - User Manual

Guidance on locating and connecting the Galvanic Unit to a treatment area and power source.

Important warnings regarding high voltage, servicing, and environmental conditions for safe operation.

Analog meter displaying actual current flow in DC Milliamperes through the patient circuit.

Selects the meter scale (0-10 or 0-50) for indicating current flow, affecting reading accuracy.

Red LED that illuminates when a completed patient circuit and active current flow are detected.

Rocker-type switch to turn the Galvanic Unit ON or OFF.

Adjusts the desired current level, with actual output indicated on the DC Milliamperes meter.

Allows reversing polarity (NOR/REV) without swapping patient cord plugs (units made after 1/1/2005).

Two banana jacks (RED positive, BLACK negative) for connecting patient cords.

Details including device name, manufacturer, power source, fuse rating, output modes, and voltage/current ranges.

Information on meter accuracy, leakage current limits, and electrical safety certifications.

Device requires minimal maintenance, focusing on regular inspection of the unit and accessories.

Annual inspection covering line cord, plugs, panel controls, and cabinet integrity.

Semi-annual inspection of patient cords, plugs, and electrodes for wear or damage.

Verification of input voltage (105-120 VAC) and reliable ground connection integrity.

Measurement of ground leakage current (chassis/patient) to ensure safety limits are met.

Optional test applying high voltage to check insulation integrity (1250 VAC).

Tests for minimum/maximum output, and verification of meter readings at specified scales (0-10 and 0-50).

Optional measurement of AC ripple in the output current using an oscilloscope (0-0.5 Vpp).
