5. Gosod

5.1 Gosod Batri

Gwnewch yn siŵr bod y multimedr wedi'i ddiffodd a bod y gwifrau prawf wedi'u datgysylltu.
Lleolwch glawr adran y batri ar gefn y mesurydd.
Dadsgriwiwch y sgriw(iau) cadw a thynnwch y gorchudd.
Insert two 1.5V AAA batteries, observing correct polarity (+ and -).
Rhowch glawr adran y batri yn ôl a'i sicrhau gyda'r sgriw(iau).

5.2 Cysylltu Gwifrau Prawf

Mewnosodwch y wifren brawf ddu i mewn i'r jac mewnbwn "COM" (Cyffredin).
Ar gyfer y rhan fwyaf o fesuriadau (Cyf.tage, Resistance, Continuity, Diode, Frequency, Duty Cycle), insert the red test lead into the "VΩHz" input jack.
Ensure test leads are fully inserted before taking measurements.

6. Cyfarwyddiadau Gweithredu

The MS8301D uses a rotary switch to select the primary measurement function and function buttons for secondary selections or features.

6.1 Gweithrediad Cyffredinol

Pŵer ymlaen / i ffwrdd: Rotate the function switch from "OFF" to any desired measurement function to turn on the meter. Rotate back to "OFF" to power off. The meter also features Auto Power Off.
Golau cefn: Press the backlight button (often labeled with a light bulb icon) to illuminate the display.
Daliad Data: Pwyswch y botwm "HOLD" i rewi'r darlleniad cyfredol ar yr arddangosfa. Pwyswch eto i ryddhau.
MAX / MIN: Press the "MAX/MIN" button to enter MAX/MIN recording mode. The meter will display the maximum or minimum value detected. Press again to cycle through MAX, MIN, and current readings.

6.2 Swyddogaethau Mesur

Always ensure the correct function is selected and test leads are connected to the appropriate input jacks before making measurements.

DC Cyftage Measurement (V DC):
- Rotate the switch to the "V" position. The meter will automatically select DC or AC. If needed, press the "FUNC" button to select DC.
- Cysylltwch y plwm prawf coch ag ochr bositif (+) y gylched a'r plwm prawf du â'r ochr negatif (-).
- Darllenwch y cyftage gwerth ar yr arddangosfa.
AC Cyftage Measurement (V AC):
- Rotate the switch to the "V" position. The meter will automatically select DC or AC. If needed, press the "FUNC" button to select AC.
- Cysylltwch y gwifrau prawf ar draws y cyfaint ACtage ffynhonnell.
- Darllenwch y cyftage gwerth ar yr arddangosfa.
Resistance Measurement (Ω):
- Rotate the switch to the "Ω" position.
- Gwnewch yn siŵr bod y gylched wedi'i dad-egnïo cyn mesur gwrthiant.
- Cysylltwch y gwifrau prawf ar draws y gydran i'w mesur.
- Darllenwch y gwerth gwrthiant ar yr arddangosfa.
Continuity Test (with audible buzzer):
- Rotate the switch to the "Ω" position and press "FUNC" until the continuity symbol appears.
- Gwnewch yn siŵr bod y gylched wedi'i dad-egni.
- Connect the test leads across the circuit or component. An audible beep indicates continuity (low resistance).
Diode Test (diode function):
- Rotate the switch to the "Ω" position and press "FUNC" until the diode symbol appears.
- Cysylltwch y wifren brawf goch â'r anod a'r wifren brawf ddu â chatod y deuod.
- Bydd yr arddangosfa'n dangos y gyfrol ymlaentage gollwng. Gwrthdrowch y gwifrau; mae darlleniad cylched agored (OL) yn dynodi deuod da.
Frequency (Hz) and Duty Cycle (%) Measurement:
- Rotate the switch to the "Hz%" position.
- Cysylltwch y gwifrau prawf ar draws y ffynhonnell signal.
- The display will show the frequency. Press "FUNC" to switch to duty cycle measurement.
Cyf. Di-gyswllttagCanfod e (NCV):
- Rotate the switch to the "NCV" position.
- Move the top front part of the meter near the conductor.
- Bydd y mesurydd yn dangos presenoldeb cyfaint ACtage with an audible beep and/or visual indicator.
