Introduction
Overview
The PCE-CM 5 is a portable, hand-held professional meter that measures AC/DC voltage, AC/DC current, resistance, capacitance, diodes, continuity, frequency, duty cycle, temperature and non-contact voltage. This meter is easy to use with one hand, suitable for professional users or amateurs, and ideal for school or home use.
Precautions:
Users must follow standard safety instructions while using the meter:
1. Once the meter is out of the package, check for any damage to the meter before using.
2.
Double check the meter to make sure all the components are in good condition.
3.
Check the test leads before operation. Check the test leads for damage to the insulation or wires before use.
4.
Use the original test leads included in the package for best performance and safety. If necessary, use compatible leads with same specifications as the originals.
5.
Make sure to set the meter to the correct functions and measuring range before taking measurement.
6.
Do not use the meter on a circuit where the measuring
range is over the capable range specified in the user’s manual.
7.
Do not touch the tips of the test leads when performing measurement.
8.
If the measurement is above 60V DC or 30V AC, make sure to keep fingers behind the barrier and finger guards.
9.
Do not use the meter on a circuit if the voltage is above
600V.
10.
In manual mode, if the value to be measured is unknown, start the meter in the maximum range and then adjust accordingly.
11.
Remove the leads from the circuit first before switching between functions.
12.
Disconnect power and discharge all capacitors before
measuring resistance, capacitance, continuity or diodes.
13.
Do not measure capacitance before the capacitors
are discharged.
14.
Do not operate the meter near explosive gas, vapor
or dust.
15.
Stop using the meter if the meter or test leads appear
damaged or do not function properly.
16.
Do not use the meter unless the battery case is securely
fastened to the back of the meter.
17.
Do not expose the meter to direct sunlight, heat, or moisture.
