1. INTRODUCTION

The MT935 is a handheld, battery-operated meter designed to detect the

rotary field of three-phase systems and determine motor-rotation direction.

2. SYMBOLS

The following symbols appear on the Meter or in this manual.

Risk of electric shock

Risk of Danger, Important information see manual.

Hazardous Voltage.

Equipment protected by double or reinforced insulation

Battery

Earth

AC or DC

Conforms to EU directives

Overvoltage (Installation) Category III. Pollution Degree 2 per

ICE 1010-1 refers to the level of Impulse withstand voltage

protection provided. Equipment of Overvoltage Category III is

equipment in fixed installations (e.g. electricity meter and

primary over-current protection equipment).

3. SAFETY INFORMATION

CAUTION identifies conditions & actions that may damage the meter.

WARNING identifies conditions & actions that pose hazard to the

user. To avoid possible electric shock or fire, do the following:

• Read the safety information carefully before using or servicing this meter.

• Adhere to local and national safety codes.

• Individual protective equipment must be used to prevent shock and

injury.

• Using this meter in a manner not specified by Major Tech may impair

safety features/protection provided by the equipment.

• Avoid working alone.

• Inspect the test leads for damaged insulation or exposed metal. Check

test lead continuity, damaged leads must be replaced, do not use the

meter if it appears to be damaged.

• Be careful when working above 30V AC RMS, 42V AC peak and 60V DC,

such voltages pose a shock hazard.

• When using the probes, keep fingers away from probe contacts, keep

fingers behind the finger guards on the probes.

• Measurements can be adversely affected by impedances of additional

operating circuits connected in parallel or by transient currents.
