Introduction
Overv iew
The MS 260 1 is a po rtabl e, ha nd- held profe ssi ona l meter
that m eas ure s AC/DC vo lta ge, AC /DC curren t, re sistance ,
capa cit anc e, diod es, c ont inuity, frequ enc y, du ty cy cle ,
temp era tur e and non -co nta ct voltage . Th is me ter i s easy
to use w ith o ne ha nd, sui tab le fo r professi ona l use rs or
amat eur s, an d ideal f or sc hoo l or home use.
Prec aut ion s:
User s mus t fol low sta nda rd sa fety in str uct ions while
usin g the m ete r:
1. Onc e the m ete r is out of t he pa cka ge, che ck fo r any
dama ge to t he me ter bef ore u sin g.

2. Dou ble c hec k the met er to m ake s ure all the
comp one nts a re in goo d con dit ion.
3. Che ck th e tes t leads b efo re op eration. C hec k the test
lead s for d ama ge to the i nsu lat ion or wires b efo re use.
4. Use t he or igi nal tes t lea ds in cluded in th e pac kag e for
best p erf orm ance an d saf ety. If ne ces sary, use
comp ati ble l eads wi th sa me sp ecificat ion s as the
orig ina ls.
5. Make sure to set the meter to the correct functions and
measuring range before taking measurement.
6.Do not use the meter on a circuit where the measuring
range is over the capable range specified in the user ’s
manual.
7. Do not touch the tips of the test leads when performing
measurement.
8. If the measurement is above 60V DC or 30V AC, make
sure to keep fingers behind the barrier and finger guards.
9. Do not use the meter on a circuit if the voltage is above
600V.
10. In manual mode, if the value to be measured is
unknown, start the meter in the maximum range and
then adjust accordingly.
11. Remove the leads from the circuit first before switching
between functions.
12. Disconnect power and discharge all capacitors before
measuring resistance, capacitance, continuity or diodes.
13. Do not measure capacitance before the capacitors
are discharged.
14. Do not operate the meter near explosive gas, vapor
or dust.
15. Stop using the meter if the meter or test leads appear
damaged or do not function properly.
16. Do not use the meter unless the battery case is securely
fastened to the back of the meter.
17. Do not expose the meter to direct sunlight, heat, or
moisture.
