Do not operate the ENGINEER DMM with the battery cover off as this will compromise the
insulated safety barrier. Do not use the tester in unfavourable environments such as:
●
Wet conditions or in high humidity
●
Dust and flammable gasses, vapours or solvent
●
Thunderstorms or similar conditions such as electrostatic fields
2. Description
The ENGINEER DMM is a 6000 count, True RMS Digital Multimeter featuring non contact
voltage detection, temperature measurement and back lit LCD. Other functions include
resistance, diode test, continuity check, capacitance and frequency.
