Safety Warnings
●
Read and understand the User's guide and Safety warnings before using this equipment.
●
Follow Safety procedures and rules for working near high voltage energized systems during
the use of this equipment. The generated voltages may be dangerous.
●
Do NOT connect or disconnect the test leads during the measurement.
●
Be careful not to make short-circuit between the terminals while a measurement is
running, because it could be dangerous for the operator. Be sure that there is not a
voltage difference between the points to which the megohmmeter will be connected, nor
between them and ground.
●
The panel, terminals, and connectors of the equipment must stay dry and clean.

PM1A
Description
The PM1A is easy-to-use equipment that provides reliable, safe, and accurate measurements of
insulation resistances up to 200 GΩ, with 3 test voltages: 250 V - 500 V - 1kV.
Furthermore, it offers useful additional features: 200 mA continuity range, low resistance measurement,
AC/DC voltage measurement up to 600 V, selectable timer, hold memory, and selectable resistance limits for
pass-fail testing, with sound (beep) indication.
To guarantee operator safety, there are no accessible metallic parts. Output terminals are placed in the
furthest and most protected area of the equipment, and a light indicator shows high-voltage presence. Due
to its reduced dimensions, weight, and power supply autonomy, this equipment is suitable for fieldwork. It is
easy to carry, simple to operate.

3. Indicates the unit of measured value showed in the display.
4. Indicates the selected test voltage.
WARNING: Do NOT connect the test leads during the measurement or when the HV LED
is lit.
Power Supply
The PM1A uses a rechargeable Ni-MH battery for power (4 x 1.2 V)
WARNING: Use ONLY rechargeable batteries, Ni-MH AA size, 1.2 V each, with a
capacity of 1.3 Ah up to 2.5 Ah. It is dangerous to use any other type of batteries!

Low Battery Indication
When the battery charge reaches a minimum value, approximately 10%, the
message “LO BAT” appears automatically in the display.
Charging the Battery
To recharge the battery:
●
Check if the PM1A is turned OFF.
●
Connect the equipment to the mains using the external power
supply.
●
The battery LED
will continue lighting with a red light until
completing the charge. It then changes to a green light, remaining
on until equipment is disconnected from the mains supply. The
average time to fully charge the battery is approx.5 hours.
Battery connected to Mains
NOTE: The battery loses part of its charge while being stored. Before using the insulation tester for the first
time, or after a period when stored, the battery should be recharged.
