1. Introduction
Warning
Read"Safety Information"before using the meter. ProcessMeter ( referred to as "the meter ")is a handheld,
battery-operated tool for measuring electrical parameters. It has all the features of a digital multimeter, it
could also output signals of direct voltage, current and frequency as well.
If the meter is damaged or something is missing, contact the place of purchase immediately. Contact a
distributor for information about DMM (digital multimeter) accessories.
2. Safety Information
The meter complies with IEC61010.1-93 Overvoltage CategoryII.Use the meter only as specified in this
manual, otherwise the protection provided by the meter may be impaired. A Warning identifies conditions
and actions that pose hazard(s) to the user; a Caution identifies conditions and actions that may damage
the meter or the equipment under test; an Attention identifies symbols of the operation and explanations
of the features. International symbols used on the meter and in this manual are explained below.
Warning
To avoid possible electric shock or personal injury:
• Do not use the meter if it is damaged. Before using the meter, inspect the case. Look for cracks or
missing plastic. Pay particular attention to the insulation surrounding the connectors.
• Make sure the battery door is closed and latched before operating the meter.
• Remove test leads from the meter before opening the battery door.
• Inspect the test leads for damaged insulation or exposed metal. Check test leads before using the
meter.
• Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the
meter serviced.
• Do not operate the meter around explosive gas, vapor, or dust.
• Use only type AAA batteries, properly installed in the meter case to power the meter.
• When servicing the meter, use specified replacement parts.
• Use caution when working above 30V ac rms, 42V ac pk, or60V dc. Such voltages pose a shock hazard.
• When using the probes, keep fingers behind the finger guards on the probes.
• Connecting the common test lead before connecting the live test lead. When disconnecting test leads,
disconnect the live test lead first.

    • Do not touch the charging connector when the test lead is connected. Caution! To avoid possible damage to meter or to equipment under test: • Disconnect the power and discharge all high-voltage capacitors before testing resistance or continuity. • Use the proper jacks, function, and range for the measurement or sourcing application.

    5. Ranges A measurement range determines the highest value and resolution at which the meter can measure. Most meter measurement functions have more than one range (see “Specifications”). Make sure the correct range is selected: - If the range is too low, the display shows OL (overload). - If the range is too high, the meter will not be displaying its most precise measurement.

    9. Measuring Frequency, Duty Cycle Ratio Press <Hz> to show Frequency, Duty Cycle Ratio and Voltage (Current) in sequence when measuring voltage (DC mV voltage excluded) and current. 10. Output Function The output terminal of the meter produces DC voltage, frequency, current and simulating transmitter set by the user.

    13. Simulating Transmitter output (absorption current) XMT refers to simulate a current loop circuit transmitter with the meter. Do this when you get external dc voltage (5-28 V) or have current loop in series. Caution! Set the rotary button in one of the mA output before connecting the testing leads with current loop circuit. Otherwise, low impedance from other parts of rotary will occur in the circuit and caused 35mA current in circuit.

    • Reinstall the battery door and tighten screws. • Install the protector. Caution! Make sure the battery’s odes are in accordance with the symbols illustrated in battery pool when replacing them. 17. Replacing a Fuse Warning To avoid personnel injury or damage to the meter, use only the specified replacement fuse. F1 the specifi- cation is 63mA 250V and F2 is 0.5A 250V, which are fast-melt.
