CME Equipment Operation & Maintenance 3

Question 1

What does 'epilator impedance' refer to in the context of electrolysis equipment?

Accepted Answer

The opposition to current flow measured at the probe-tissue interface

Answer

The resistance of the machine's internal power supply

Answer

The frequency response of the RF oscillator circuit

Answer

The thermal resistance of the handpiece insulation

Question 2

A probe holder (handpiece) that feels warm during extended treatment sessions should be:

Accepted Answer

Inspected for internal short circuits and removed from service if overheating persists

Answer

Considered normal as long as temperature remains below 60°C

Answer

Cooled with a damp cloth between clients to maintain efficiency

Answer

Operated at lower intensity settings to compensate for heat buildup

Question 3

Which sterilization method is NOT appropriate for stainless steel electrology probes?

Accepted Answer

Immersion in 70% isopropyl alcohol for 10 minutes

Answer

Dry heat oven at 160°C for one hour

Answer

Autoclave steam sterilization

Answer

Chemical vapor sterilization (Chemiclave)

Question 4

When calibrating a new epilator, the electrologist should verify:

Accepted Answer

That the unit's output matches manufacturer-specified milliamperage at each intensity setting

Answer

That the probe holder reaches body temperature before insertion

Answer

That the RF frequency exceeds 27 MHz for optimal tissue heating

Answer

That galvanic and thermolysis circuits are operating simultaneously at all times

Question 5

A client reports feeling stinging or burning sensations well outside the treatment area during galvanic electrolysis. This most likely indicates:

Accepted Answer

Poor contact or concentration of current at the indifferent electrode site

Answer

The galvanic current intensity is set appropriately for the hair type

Answer

The indifferent electrode is placed too far from the treatment area

Answer

The probe is inserted at the correct angle and depth

Question 6

The purpose of the footswitch (foot pedal) on an electrolysis unit is to:

Accepted Answer

Allow hands-free activation of current while the operator positions the probe

Answer

Adjust current intensity during treatment

Answer

Control the timer duration for each insertion

Answer

Switch between galvanic and thermolysis modalities

Question 7

Which of the following probe materials requires extra care to avoid corrosion during autoclave sterilization?

Accepted Answer

Insulated probes with nylon coating

Answer

Solid gold probes

Answer

Stainless steel probes

Answer

Disposable steel Ballet probes
