WARNING

Make sure to read an d follo w all saf ety pro cedures
to avoid electri c shock a nd/or i njury.

The MS2030 is a safe , relia ble, ye t small handheld 3 ½
digit dig ital cl amp met er. Capa ble of measuring AC
current, AC/DC vo ltage , resis tance, diode’s forw ard
voltage drop, an d conti nuity, it’s i deal fo r both home
users and profes siona ls.

2.Safety Inst ru ctions

The MS2030 meets E N6101 0-1 saf ety requiremen ts for
electrical tes ting in strum ents and handhel d digit al
multimeters. I t’s d esigned to compl y with EN 61010 -1
with a CAT III 600V safety ra ting an d pollu tion degree of 2.

• All safety guidel ines ou tline d should be follow ed
otherwise the pr otect ion pro vided by the instr ument
may be impaired.

• War ning sy mbols in the manua l alert u sers of p otential
dangerous situ ation s.

• Precautions ar e to prev ent the u ser from damagin g
the instrument o r the tes t objec t.

2.1 Precaution s

To avoid poss ible el ectri c shock , personal injur y or
damage to the mete r, pleas e obser ve the following :

1. Before using th e meter, c heck th e meter for damage
during transpo rt.

2. Check the test le ads for d amage t o the insulation o r
wires before use .

3. Ensure the mete r works p roper ly by testing a know n
voltage first. I f not wor king pr operl y, have th e meter
serviced befor e using .

4. Never exceed th e prote ction l imit values indi cated
in the specifica tions f or each r ange of measurem ent.

5. Always use cauti on when m aking v oltage
measurements a bove 60 V dc or 30V a c rms.

6. Make sure to use th e corre ct inpu t jack, function a nd
range when measu ring.

7. Do not place the me ter in an y envir onment with dust ,
explosive gas or v apor.

8. Always keep fing ers beh ind the p robe barriers.

9. Connect the com mon tes t lead fi rst, th en the hot le ad.
Disconnect in re verse o rder.

10. Turn off powe r and dis charge capacit ors bef ore
measuring resi stanc e, diod es or continuity.

11. Fail ure to fo llow sa fety guideline s may pre vent th e
meter’s b uilt in protecti on from w orkin g properly.

12. To avoid d amage o r incorre ct read ings, c heck fo r AC
voltage presen t befor e makin g DC voltage
measurements .

13. Do not use the met er with t he batt ery cover not
securely in plac e.

14. When the “ ”symb ol appe ars, re place t he batter ies
to avoid incorre ct read ings

15. Before openi ng the ca se, alw ays disconnect t est
leads from all ene rgize d circu its.

16. Only use the tes t leads p rovid ed with the meter.
Replace only wit h simil ar lead s with matching
specificatio ns.

17. Do not touch inp ut jack s durin g measurement to
avoid electric s hock.

18. Before switc hing fu nctio ns, remove test le ads fro m
an circuit.

Tip s for mea suring resista nce:

- Sometimes the re sisto r value a nd measured resi stanc e
diffe r.This i s due to th e meter’s o utput test curre nt goes
through all poss ible pa ths bet ween leads.

- For low resistan ce meas ureme nts, short the tes t leads
and record the res istan ce disp layed. Then co nnect t o
the circuit and su btrac t the rec orded resistan ce from
the measuremen t for the m ost acc urate r esults.

WARNING

To avoid i njury o r damag e to the me ter, make su re
to turn off all powe r and dis charg e all cap acitors
before measuri ng resi stanc e.

4.6 Continuity

1. Turn off all pow er and di scharge capaci tors on t he
circuit under te st.

2. Insert the red te st lead i n the “IN PUT” ja ck and the
black lead in the “C OM” jac k.

3. Move the rotary s witch t o the pos ition . Connect
the test leads acr oss the c ircui t to be mea sured.

4. Read measured r esist ance on t he display. If th e
measured resis tance i s less th an 70Ω, the meter’s
buzzer will soun d.

WARNING

To avoid i njury o r damag e to the me ter, make su re
to turn off all powe r and dis charg e all cap acitors
before measuri ng cont inuit y.

4.7 Diode Test

1. Turn off all pow er and di scharge capaci tors on t he
circuit under te st.

2. Insert the red te st lead i n the “IN PUT” ja ck and the
black lead in the “C OM” jac k.

3. Move the rotary s witch t o the pos ition . Connect
the test leads acr oss the c ircui t to be mea sured.

4.Read the measu red for ward bi ased voltage dro p on the
display. If the l eads ar e reversed, only “ 1” is dis playe d.

WARNING

To avoid i njury o r damag e to the me ter, make su re
to turn off all powe r and dis charg e all cap acitors
before measuri ng diod es.
