SAFETY INFORMATION
The following safety information must be observed to insure maximum personal safety during the operation
at this meter:
•Do not use the meter if the meter or test leads look damaged, or if you suspect that the meter is not
operating properly.
•Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes,
outlets, fixtures, etc., which might be at ground potential. Keep your body isolated from ground by
using dry clothing, rubber shoes, rubber mats, or any approved insulating material.
•Turn off power to the circuit under test before cutting, unsoldering, or breaking the circuit. Small
amounts of current can be dangerous.
•Use caution when working above 60V dc or 30V ac rms. such voltages pose a shock hazard.
•When using the probes, keep your fingers behind the finger guards on the probes.
•Measuring voltage which exceeds the limits of the multimeter may damage the meter and expose the
operator to a shock hazard. Always recognize the meter voltage limits as stated on the front of the
meter.
•Never apply voltage or current to the meter that exceeds the specified maximum:
SAFETY SYMBOLS
This symbol adjacent to another symbol, terminal or operating device indicates that
the operator must refer to an explanation in the Operating Instructions to avoid
personal injury or damage to the meter.
This WARNING symbol indicates a potentially hazardous situation, which if not
avoided, could result in death or serious injury.
This CAUTION symbol indicates a potentially hazardous situation, which if not
avoided, may result damage to the product.
This symbol advises the user that the terminal(s) so marked must not be connected
to a circuit point at which the voltage with respect to earth ground exceeds (in this
case) 1000 VAC or VDC.
This symbol adjacent to one or more terminals identifies them as being associated
with ranges that may, in normal use, be subjected to particularly hazardous voltages.
For maximum safety, the meter and its test leads should not be handled when these
terminals are energized.

OPERATION
WARNING
RISK OF ELECTROCUTION.HIGH-VOLTAGE CIRCUITS,BOTH AC AND DC, ARE VERY DANGEROUS AND SHOULD BE
MEASURED WITH GREAT CARE.
1. ALWAYS turn the function switch to the OFF position when the meter is not in use. This meter has
Auto OFF that automatically shuts the meter OFF if 15 minutes elapse between uses.
2. If “OL” appears in the display during a measurement, the value exceeds the range you have selected.
Change to a higher range.
NOTE: ON SOME LOW AC AND DC VOLTAGE RANGES,WITH THE TEST LEADS NOT CONNECTED TO A DEVICE,THE
DISPLAY MAY SHOW A RANDOM,CHANGING READING.THIS IS NORMAL AND IS CAUSED BY THE HIGH-INPUT
SENSITIVITY.THE READING WILL STABILIZE AND GIVE A PROPER MEASUREMENT WHEN CONNECTED TO A CIRCUIT.
MODE BUTTON
To select Diode/Continuity or DC/AC current
RANGE BUTTON
When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects the
best range for the measurements being made and is generally the best mode for most measurements. For
measurement situations requiring that a range be manually selected, perform the following:
1. Press the RANGE button. The “AUTO” display indicator will turn off.
2. Press the RANGE button to step through the available ranges until you select the range you want.
3. Press and hold the RANGE button for 2 seconds to exit the ManualRanging mode and return to
AutoRanging. (If backlight is turn on, please press BACKLIGHT button it will turn off)

DATA HOLD BUTTON
The Data Hold function allows the meter to "freeze" a measurement for later reference.
1. Press the DATA HOLD button to “freeze” the reading on the indicator. The indicator “HOLD” will be
appear in the display.
2. Press the DATA HOLD button to return to normal operation.
RELATIVE BUTTON
The relative measurement feature allows you to make measurements relative to a stored reference value. A
reference voltage, current, etc. can be stored and measurements made in comparison to that value. The
displayed value is the difference between the reference value and the measured value.
1. Perform any measurement as described in the operating instructions.
2. Press the RELATIVE button to store the reading in the display and the "REL" indicator will appear on
the display.
3. The display will now indicate the difference between the stored value and the measured value.
4. Press the RELATIVE button to return to normal operation.
BACKLIGHT BUTTON
1. Press the BACKLIGHT button 2 seconds the display light ON
2. Press BACKLIGHT button again to exit the light mode.
Hz/%duty BUTTON
Press Hz/Duty Button to choose Frequency or Duty Cycle in the range of Frequency; Press Hz/%Duty
Button to measure Frequency or Duty Cycle while measures voltage or Current, the Voltage/Current
requirement and range of Frequency see the following form, press Hz/%Duty Button to return to
measurement of Voltage or Current.

INFORMAZIONI DI SICUREZZA
Osservare le seguenti informazioni sulla sicurezza per garantire la sicurezza personale dell'operatore con lo
strumento:
•Non usare lo strumento o i suoi terminali se sono danneggiati, o se vi è il sospetto che lo strumento
non lavori in modo corretto.
•Non mettersi mai collegati a terra quando si fanno misure elettriche. Non toccare parti metalliche
esposte, prese, cavi ecc. che potrebbero essere potenzialmente collegati a terra. Tenere il proprio
corpo isolato da terra utilizzando vestiti asciutti, scarpe in gomma, tappeti in gomma o qualsiasi altro
materiale che sia stato certificato come isolante.
•Togliere sempre alimentazione al circuito sotto misura prima di effettuare tagli, dissaldature o
interruzione di circuiti. Piccole quantità di corrente possono essere pericolose.
•Usare cautela quando si lavora con tensioni oltre i 60V CC o i 30 V CA RMS; tali tensioni possono
provocare scosse pericolose
•Tenere sempre le dita dietro la zona di sicurezza delle sonde quando si utilizzano con lo strumento.
•La misura di tensioni che superano i limiti dello strumento può danneggiare il multimetro ed esporre
l'operatore a scosse pericolose. Tenere sempre presente i limiti operativi del multimetro come indicato
sulla parte frontale dello strumento

Questo simbolo, adiacente ad un altro simbolo, a un dispositivo o apparecchio in
funzione indica che l'operatore deve far riferimento alle spiegazioni presenti nel
manuale d'uso per evitare lesioni personali o il danneggiamento dello strumento.
Il simbolo WARNING indica una situazione potenzialmente a rischio, che se non
evitata può provocare la morte o serie lesioni personali.
Il simbolo CAUTION indica una situazione potenzialmente pericolosa, che se non
evitata può danneggiare lo strumento.
Questo simbolo avvisa l'operatore che il/i terminale/i così evidenziati possono non
essere collegati a punti del circuito in cui il voltaggio rispetto alla messa a terra
eccede (in questo caso) i 1000 V CA o CC.
Questo simbolo, adiacente ad uno o più apparecchi, li identifica come operativi a
range di lavoro che, nell'utilizzo normale, possono essere soggetti a tensioni
particolarmente pericolose. Per la massima sicurezza, lo strumento e i suoi contatti
non devono essere tenuti in tensioni insieme a questi apparecchi.
