Page 4: Introduction
PM55 offers VolTect™, a built-in non-contact voltage detection of AC voltage. Although very small, this meter is fully UL safety rated to CAT III levels and is UL listed. The Meterman PM55 precision meter includes measurement extras such as capacitance, frequency, DC microamps and safety extras such as transient protection to 4 kV and overload protection to 600 V. -

Page 6: Making Measurements
Making Measurements All measurements described in this manual use the Red test lead for positive (+) polarity and Black test lead for Ground reference (-) unless otherwise specified AutoTect mode is the default function in Auto V.Ω position. Press the SELECT button momentarily to select and step through the functions: •... -
Page 7: Autotect Mode
AutoTect Mode This AutoTect feature automatically selects measurement function of V dc, V ac, or resistance based on the input via the test leads. ● With no input, the meter displays Auto when it is ready. ● With no voltage signal but a resistance below 6 MΩ is present, the meter displays the resistance value. -
Page 8: Electric Field Ef-Detection, Voltect
Electric Field EF-Detection, VolTect With Auto displayed on the LCD, press the SELECT button momentarily 2 times to select the EF-Detection feature. The meter displays EF when it is ready. Signal strength is indicated as a series of bargraph segments on the display and variable beep tones. - Page 9 Note For Maximum sensitivity, hold the meter away from the VolTect corner.

Voltage With Auto on the LCD, press the SELECT button 3 times to select V ac function. The meter displays LoZBV when it is ready.This function is auto-ranging. With Auto on the LCD, press the SELECT button 4 times to select V dc. The meter displays LoZ V when it is ready. -
Page 11: Diode
Diode Turn the rotary selector to the GR /600 Ω position. Diode test is the default function. The reading shows the approximate voltage drop across the test leads. Normal forward voltage drop (forward biased) for a good silicon diode is between 0.400 V to 0.900 V. A reading higher than that indicates a leaky diode (defective). -
Page 12: Troubleshooting
Troubleshooting If the instrument fails to operate, check battery, leads, and replace battery as necessary. Double-check operating procedure as described earlier in this manual. If the display locks up, press the SELECT button for approximately 6 seconds to reset the microprocessor. If the instrument voltage-resistance input is subjected to high voltage transient (mostly caused by lightning or switching surge to your system) by accident or abnormal conditions of operation, the series fusible resistors... -
