Mitchell MITHD9 AC Hotstick Voltage Detector – a safety device designed for first responders which provides warning of exposed high voltage AC from a safe distance.

Mitchell MITHD9 AC Hotstick Voltage Detector.

The AC HotStick will give early audible (“beeping”) and visual (flashing LED) warning of the presence of dangerous voltages without the need to contact the surface carrying the current. The closer the user comes to the source of the voltage, the more rapidly the unit beeps and flashes.

– The AC Hotstick consists of a high sensitivity AC amplifier for the frequency range 50/60Hz and AC voltage detection above 100Vac

– The AC Hotstick has 3 sensitivity settings:

1. High sensitivity setting – allows the detection of AC from the greatest distance

2. Low sensitivity setting – the overall sensitivity is reduced. This aids in detecting the source of the signal

3. Front focused setting – allows pinpointing a source. In this mode a small sensor in the front is shielded from signals coming from the sides. This makes the unit directional and the influence of e.g. high voltage wires overhead is greatly reduced.

• • Verify correct power shutdown, lockout, tag out, disconnects.
  • Locate hidden sources of dangerous AC from a safe distance without making physical contact
  • Identify power line back feeds from generators and energized pools of water.
  • Check downed power lines for a safe environment for vehicular rescues.
  • A safe and simple tool for all emergency personnel to use in the field.
  • Comply with EN61326-1
  • IP66 rated for dust and water intrusion
  • 21″ length ensures user is physically separated from live lines

The AC Hot Stick consists of a high sensitivity AC amplifier for the frequency range below 100 Hz.

The special logarithmic amplifier is capable of receiving AC signals over a very wide amplitude range. Such signals, emanating from an unshielded, voltage-carrying surface, can be made audible and visible as a warning.

The warning signals (beeps and LED flashes) will increase when the signal increases as the AC Hot Stick approaches the source.

This makes it possible to locate the source quickly.

In the presence of high tension wires the sensitivity can be reduced by selecting the Low sensitivity or the Front Focused mode.

The sensing section of the AC Hot Stick is located in the red striped area.

When used in the High or the Low sensitivity mode the unit will respond to signals from all sides (is omni-directional).

When the Front Focused mode is selected the unit responds only to signals received from the front of the AC Hot Stick.

This reduces the sensitivity and concentrates pickup into a small frontal area.

This permits pinpointing of the source and distinguishing between adjacent wires.

The detector will not respond to DC voltages from car batteries or from the third rail in light rail transit vehicles operating on DC.

The unit features a complete self-test circuit: Immediately after turn-on, a built-in low frequency oscillator will operate for about 3 seconds simulating power line signals.

This provides a separate test signal to the input.

Rapid beeping indicates proper operation of the set.

Additional Sensitivity Levels Include Low Sensitivity and Focused Setting. (With Self-Testing function) Signal indication includes audible beep and visual LED.
