Chapter 1. Introduction
Warning
Read Safety Information before using the meter.
Summarize
The meter is a handled, battery-operated tool for measuring electrical parameters. It has all the features of a digital millimeter
and measure AC voltage, DC voltage, AC current, DC current, resistance, capacitance, frequency, duty cycle ratio, dBm, TC,
RTD,
Diode Test,
and
Continuity Check
.
Besides, it has features like:
Large LCD screen could display the three characteristic of one input signals.
Different reference impedance for dB measure function.
AUTO HOLD, DISPLAY HOLD and PEAK HOLD to display the measuring value.
Panel calibration function.
Three convenient data recording modes: LOG mode, MANUAL mode, and COMP mode.
USB-IR jack to connect with a PC
Open-case Inspection
Open the case to check, if the meter is damaged or something is missing, contact the place of purchase immediately. Contact
the distributor for information about DMM accessories.
Accessories: A copy of user’s manual
A set of
CF-733370
industrial test lead
One USB to UART Bridge Controller (USB_DMM)
DMMVIEW_ A disk
Options: K-TYPE TC
Safety Information
The meter complies with IEC61010.1-93 Over voltage Pollution Degree 2. 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 hazards to the user.
A
Caution
identifies conditions and actions that may damage the meter or the equipment under test.
A
Notice
identifies symbols of the operation and explanations of the features. International symbols used on the meter and in
this manual are explained in Table 1-1.
Warning
To avoid possible electric shock or personal injury, follow these guidelines.
Use the meter as the instructions of the producer; otherwise, the protective function shall be invalid.
Do not use the meter if it is damaged. Before you use the meter, inspect the case. Look for cracks or missing plastic.
Pay particular attention to the insulation surrounding the connectors.
Take the leads off the meter before unlock the battery door.
Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged
test leads before you use 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.
Do not apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and
earth ground.
Make sure the meter works normally as per testing a known voltage. Do not use the meter if it operates abnormally.
When in doubt, have the meter serviced.
To avoid possible electric shock caused by false reading due to exist ting alternating voltage in all the direct current
functions, including manual and auto ranging, make sure whether there is any alternating voltage existing or not
before selecting a direct voltage range equals to or higher than the alternating voltage.
To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as
the low battery indicator
appears.
Do not touch the exposed wine, connector or unused input jack or circuit under test when the meter is working.
Use only type AAA batteries, properly installed in the meter case to power the meter.
Use caution when working above 30 V ac rms, 42 V peak, or 60 V dc. Such voltages pose a shock hazard.
Avoid working alone.
When using the probes, keep your fingers behind the finger guards on the probes.
Connect the common test lead before you connect the live test lead. When you disconnect test leads, disconnect the
live test lead first.
To avoid possible fire or electric shock, do not connect TC with the live circuit.
