סעטאַפּ
1. באַטאַרייע ייַנמאָנטירונג
The Mastech M1015B requires one 1.5V AA battery for operation. To install or replace the battery:
- Ensure the multimeter is turned OFF and disconnect all test leads from the input terminals.
- געפינט דעם דעקל פונעם באַטעריע־אָפּטייל אויף דער הינטערשטער זייט פונעם מעטער.
- Use a screwdriver to remove the screw securing the battery compartment cover.
- קערפאַלי אַראָפּנעמען די דעקן.
- Insert the 1.5V AA battery, observing the correct polarity (+ and -) as indicated inside the compartment.

2. פֿאַרבינדן טעסט דראָטן
The multimeter comes with a pair of test leads (red and black). Connect them as follows:
- Insert the black test lead into the "COM" (Common) input jack. This is the negative (-) terminal.
- פֿאַר רובֿ באַנדtage, resistance, and diode measurements, insert the red test lead into the "VΩmA" input jack. This is the positive (+) terminal.
- For current measurements (mA), ensure the red lead is in the appropriate current jack if available, or the "VΩmA" jack if it supports the desired current range. Always verify the correct jack for the selected function to avoid damage.
אַפּערייטינג ינסטראַקשאַנז
This section provides general instructions for using the Mastech M1015B Digital Multimeter. Always refer to the specific measurement type for detailed steps.
אַלגעמיינע אָפּעראַציע טריט:
- סעלעקטירן פונקציע: Turn the rotary switch to the desired measurement function (e.g., V~ for AC Voltage, V- פֿאַר DC באַנדtage, Ω for Resistance, A- for DC Current).
- אויסקלייַבן קייט: If the meter is not auto-ranging for the selected function, choose an appropriate range that is higher than the expected measurement value.
- פֿאַרבינדן לידז: Connect the test leads to the correct input terminals on the meter and then to the circuit or component under test.
- לייענען מעסטונג: Observe the reading on the LCD display. The blue backlight can be activated for better visibility.
- דיסקאַנעקט: After measurement, disconnect the test leads from the circuit first, then from the meter.
Specific Measurement Types:
- DC Voltage Measurement (V-):
שטעלט דעם ראָטאַרי סוויטש צו דער געוואונטשער DC וואָלומעןtage range (e.g., 2.5V, 10V, 50V, 250V, 300V). Connect the red lead to the positive side of the circuit and the black lead to the negative side. Read the voltagE ווערט.
- AC Voltage Measurement (V~):
שטעלט דעם ראָטאַרי סוויטש צו דער געוואונטשער AC וואָלומעןtage range (e.g., 10V, 50V, 250V, 300V). Connect the leads across the AC voltage source. Read the voltagE ווערט.
- DC Current Measurement (mA-):
Set the rotary switch to the desired DC Current range (e.g., 10mA, 250mA). וויכטיק: The meter must be connected in series with the circuit. Disconnect power, break the circuit, insert the meter, then reapply power. Ensure the red lead is in the correct current input jack.
- קעגנשטעל מעסטונג (Ω):
Set the rotary switch to the desired Resistance range (e.g., X10, X1k). Ensure the circuit or component is de-energized before measuring. Connect the leads across the component. The meter will display the resistance value.
- Battery Test (BAT):
Set the rotary switch to the BAT position. Connect the leads to the battery terminals, observing polarity. The meter will indicate the battery's condition (e.g., "GOOD", "REPLACE").
- קאָנטינויטי טעסט:
Set the rotary switch to the continuity function (often shared with resistance or diode). Connect the leads across the circuit path. A low resistance reading or an audible beep indicates continuity.

Proper maintenance ensures the longevity and accuracy of your Mastech M1015B Digital Multimeter.
1. רייניקונג
ווישט אויס דעם מעטער'ס קעסטל מיט אדווערטייזמענטamp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals free of dirt and debris.
2. באַטערי פאַרבייַט
When the battery low indicator appears on the display, replace the 1.5V AA battery as described in the "Setup" section. Remove the battery if the meter is not to be used for an extended period to prevent leakage.
3. קאָריק פאַרבייַט
The Mastech M1015B features resettable fuses for protection. In case of an overload that trips a fuse, the meter may temporarily stop functioning for the affected range. Disconnect the meter from the circuit and allow a few moments for the fuse to reset. If the issue persists, or if the meter uses non-resettable fuses (which is not indicated for this model), consult a qualified technician or the manufacturer for service.
