1. SAFETY PRECAUTIONS AND PROCEDURES
This apparatus conforms to safety standard EN 61010, relating to electronic measuring instruments. For your own safety and that of the apparatus, you must follow the procedures described in this instruction manual and especially read all the notes
proceeded by the symbol
carefully.
WARNING WARNING
If instrument is used in way don’t conform to prescriptions of this user’s manual, all considered safety protection maybe damaged.
Take extreme care for the following conditions when measuring:
• Do not measure voltage, current under humid or wet environment.
• Do not operate the meter under the environment with explosive gas (material),
combustible gas (material), steam or filled with dust.
• Do not touch the circuit under test if no measurement is being taken;
• Do not touch exposed metal parts, unused terminals, circuits and so on;
• Do not use the instrument if it seems to be malfunctioning (i.e. if you notice
deformations, breaks, leakage of substances, absence of segments on the display and so on);
• Be careful when you measure voltages exceeding 20V as you may risk electrical shocks.
• Take care not to allow your hand to pass over the Safety Guard (see Fig.1, pos.2) on current measurements and voltage measurements using the holster.
The followings symbols are used:
Caution: Refer to the instruction manual. Incorrect use may damage the apparatus or its components.
Danger high voltage: risk of electric shock.
Double insulated meter
AC/DC Voltage or Current.
DC Voltage or Current.
Application around and removal from hazardous live conductors is permitted

TM-1016
1.1. PRELIMINARY
• This apparatus has been designed for use in an environment of pollution degree 2.
• It can be used for CURRENT, VOLTAGE and FREQUENCY measurements on
installations of surge voltage category III up to 600 V, voltage between Phase and Earth (fixed installations) and for current measures up to 400A.
• This meter is not available for non-sine wave AC signals.
• You must comply with the usual safety regulations aimed at: ♦ Protecting you against the dangerous electric current. ♦ Protecting the instrument against an incorrect operation.
• Only the leads supplied with the instrument guarantee compliance with the safety
standard. They must be in a good condition and they must be replaced, if necessary with an identical model.
• Do not test or connect to any circuit with voltage or current exceeding the specified overload protection.
• Do not perform any test with environmental condition exceeding the limits indicated in paragraphs 6.2.1.
• Check if the batteries are installed correctly.
• Prior to connecting the test probes to the installation, check that the function selector is
positioned on the required measurement.
• Check if the LCD and the range indicator show the same as the function desired.
1.2. DURING USE
Read the recommendations that follow and the instructions in this manual:
WAR WARNING NING
Non compliance with the warnings and/or the instructions for use may damage the apparatus and/or its components or injure the operator.
• Remove the clamp jaw from the conductor or circuit under test before changing the range.
• When the tester is connected to the measuring circuits, do not touch any unused terminals.
• Do not measure resistance in the presence of external voltages. Even if the circuit is protected, excessive voltage could cause the instrument to malfunction.
• When measuring current with the clamp jaws, first remove the test leads from the instrument’s input jacks.
• When measuring current, any other source near the clamp jaw could affect its accuracy.
• When measuring current, always put the conductor to be tested in the middle of the
clamp jaw to obtain the most accurate reading as referred into paragraph 4.1.2.
• While measuring, if the value remains unchanged check if the HOLD function is enabled.
1.3. AFTER USE
• Once the measurements are completed, turn the rotary switch to OFF.
• If you expect not to use the instrument for a long period of time remove the batteries.

TM-1016
1.4. DEFINITION OF MEASURING (OVERVOLTAGE) CATEGORY
The norm EN 61010: Safety requirements for electrical equipment for measurement, control and laboratory use, Part 1: General requirements, defines what a measuring category, usually called overvoltage category, is.
Circuits are divided into the following measurement categories:
• Measurement category IV is for measurements performed at the source of the
low-voltage installation.
Examples are electric meters and measurements on primary overcurrent protection devices and ripple control units.
• Measurement category III is for measurements performed in a building installation.
Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to fixed installation.
• Measurement category II is for measurements performed on circuits directly
connected to the low voltage installation.
Examples are measurements on household appliances, portable tools and similar equipment.
• Measurement category I is for measurements performed on circuits not directly
connected to MAINS. Examples are measurements on circuits not derived from MAINS, and
specially protected (internal) MAINS-derived circuits. In the latter case, transient stresses are variable; for that reason, the norm requires that the transient withstand capability of the equipment is made known to the user.
2. GENERAL DESCRIPTION
Thanks to a new development concept assuring double insulation as well as compliance with category III up to 600V you can rely on utmost safety conditions.
This instrument can perform the following measurements:
• AC current (I
AC
).
• AC uA current(I AC).
• DC uA current.(I
DC
).
• AC voltage (V
AC
).
• DC voltage (V
DC
).
• DC current (I
DC
).
• Resistance.
• Continuity Test.
• Capacitance.
• Temperature
Each of these functions can be selected by means of a 7-position rotary switch, including an OFF position. There are also the following buttons: “D-H”, ”R-H /
”, “SELECT” and “ZERO”. For their use please see paragraph 0. The selected quantity appears on a high­contrast display with unit and function indication.

3. PREPARATION FOR USE
3.1. INITIAL
This instrument has been checked mechanically and electrically before shipment. All precautions have been taken to assure that the instrument reaches you in perfect condition.
However, it is advisable to carry out a rapid check in order to detect any possible damage, which might have occurred in transit.
Check the accessories contained in the packaging to make sure they are the same as reported in paragraph 6.3.1.
3.2. SUPPLY VOLTAGE
The instrument is battery supplied; it use two batteries model 1.5V LR03 included in packaging. The batteries autonomy is about 100 hours.
The symbol "
" appears when the batteries are nearly discharged. In this case, replace
them following the instructions in paragraph 5.2.
3.3. CALIBRATION
The tester complies with the accuracy specifications listed in this manual and such compliance is guaranteed for one year, afterwards the tester may need recalibration.
3.4. STORAGE
In order to guarantee the accuracy of the measurements, after a period of storage in an extreme environmental condition, wait for the apparatus returns to normal measuring conditions (see environments specifications paragraph 6.2.1).
