Overview
This Operating Manual covers information on safety
and cautions. Please read the relevant information
carefully and strictly observe all warnings.
Warning
To avoid electric shock or personal injury, read the
“Safety Information” and “Rules for Safety Operation”
carefully before using the Meter.
Digital Bench-Type True RMS Multimeter
Model 72-1016 (hereafter referred to as “the Meter”)
has auto and manual range options with maximum
reading of 5999 counts and 3-5/6 digits which has a
unique outlook design.
In addition to all the conventional features including
DC/AC voltage, current, resistance, diode, continuity
test, capacitance, temperature 0C and 0F, transistor,
max/min, there is a data hold, low battery display, sleep
mode, RS232C serial port for easy connection with
computer to realize macro recording, monitoring and
capture of transient dynamic data, displaying change
of waveform during the measurement, providing data
and evidence to engineering technicians for scientific
research.

Safety Information
This Meter complies with the standards IEC61010: in
pollution degree 2, overvoltage category (CAT. I 1000V,
CAT.II 600V) and double insulation.
CAT III: Distribution level, fixed installation, with smaller
transient overvoltages than CAT. IV
CAT IV: Primary supply level, overhead lines, cable
systems etc.
Use the Meter only as specified in this operating manual,
otherwise the protection provided by the Meter may be
impaired.
In this manual, a Warning identifies conditions and
actions that pose hazards to the user, or may damage
the Meter or the equipment under test.
A Note identifies the information that user should pay
special attention to.
International electrical symbols used on the Meter and
in this Operating Manual are explained on page 8.

Rules For Safe Operation
Warning
To avoid possible electric shock or personal injury,
and to avoid possible damage to the Meter or to the
equipment under test, adhere to the following rules:
Before using the Meter inspect the case. Do not use
the Meter if it is damaged or the case (or part of the
case) is removed. Look for cracks or missing plastic.
Pay attention to the insulation around the connectors.
Inspect the test leads for damaged insulation or exposed
metal. Check the test leads for continuity. Replace
damaged test leads with identical model number or
electrical specifications before using the Meter.
Do not apply more than the rated voltage, as marked
on the Meter, between the terminals or between any
terminal and ground.
Prior to measurement, ensure the rotary selector
switch is in the proper position. To prevent potential
damage to the meter, do not change range or mode
during measurement.
When the Meter working at an effective voltage over
60V DC, or 30V RMS AC, special care should be
taken for there is danger of electric shock.
Use the proper terminals, function, and range for your
measurements.
If the value to be measured is unknown, use the
maximum measurement position and reduce the range
step by step until a satisfactory reading is obtained.
Do not use or store the Meter in an environment of
high temperature, humidity, explosive, flammable gas
or strong magnetic field. Do not use the meter if
allowed to get wet. Even after complete drying,
incorrect readings could occur, causing a potentially
hazardous condition.
When using the test leads, keep your fingers behind
the finger guards.
Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes,
current, or capacitance.
Before measuring current, check the Meter’s fuses
and turn off power to the circuit before connecting the
Meter to the circuit.

Replace the battery as soon as the battery indicator
appears. With a low battery, the Meter might
produce false readings that can lead to electric shock
and personal injury.
Remove test leads, temperature probe, RS232C
interface cable, and alligator clip from the Meter and
turn the Meter power off before opening the Meter
case.
When servicing the Meter, use only the same model
number or identical electrical specifications
replacement parts.
The internal circuit of the Meter shall not be altered
at will to avoid damage of the Meter and any accident.
Soft cloth and mild detergent should be used to clean
the surface of the Meter when servicing. No abrasive
and solvent should be used to prevent the surface
of the Meter from corrosion, damage and accident.
The Meter is suitable for indoor use only.
Turn the Meter power off when it is not in use.
Remove batteries from meter if use of battery power
is not anticipated for long periods of time.
Routinely check installed batteries for leaking. Remove
immediately if evidence of leaks exist.

Measurement Operation
A. DC or AC Voltage Measurement (See figure 3)
Warning
To avoid personal injury, or damage to the Meter from
electric shock, please do not attempt to measure
voltages higher than 1000V although readings may
be obtained.
To measure DC/AC voltage, connect the Meter as
follows:
Model 72-1016: OPERATING MANUAL
1.
2.
3.
Insert the red test lead into the Vterminal and the
black test lead into the COM terminal. If the measured
value is less than 600mV, insert the red test lead
into mV terminal instead and press RANGE button
to select manual range 600.0mV mode, the LCD
displays “MANUAL” and “mV”.
Set the rotary switch to V; press SELECT button
to select DC or AC measurement mode.
Connect the test leads across with the object being
measured. The measured value shows on the display.
AC measurement displays True RMS value.
(Figure 3)
This Manual: http://www.manuallib.com/file/2587080

4. Press AC/AC+DC button to measureAC+DC voltage’s
true RMS.
Note
In each range, the Meter has an input impedance of
10M except 600mV range has 3000M . This
loading effect can cause measurement errors in high
impedance circuits. If the circuit impedance is less
than or equal to 10k , the error is negligible (0.1%
or less).
When DC/AC voltage measurement has been
completed, disconnect the connection between the
test leads and the circuit under test, and remove the
test leads from the input terminals of the Meter.
