4. Uppsetning

4.1 Uppsetning rafhlöðu

1. Gakktu úr skugga um að mælirinn sé slökktur.
2. Finndu rafhlöðulokið aftan á mælinum.
3. Use a screwdriver to loosen the screw(s) and remove the cover.
4. Insert a new 9V battery, observing the correct polarity (+ and -).
5. Settu lokið á rafhlöðuhólfið aftur og festu það með skrúfunni/skrúfunum.

4.2 Tenging prófunarleiðslu

1. Fyrir voltage, resistance, and frequency measurements, insert the black test lead into the COM flugstöð.
2. Settu rauðu prófunarsnúruna í VΩHz flugstöð.
3. For specific 2-channel measurements or other functions requiring a second input, refer to the operating instructions for connecting to the CH2 flugstöð.
4. Ensure connections are secure before proceeding with measurements.

5. Notkunarleiðbeiningar

5.1 Almenn mælingaraðferð

1. Turn the rotary dial to the desired measurement function.
2. Connect the test leads or clamp the jaws to the circuit under test as appropriate for the selected function.
3. Read the measurement value(s) on the dual LCD display.
4. If the reading is unstable or out of range, adjust the function or range if manual ranging is available.

5.2 Mæling á AC/DC straumi (Clamp)

This function measures current without breaking the circuit.

1. Snúðu snúningsskífunni á A~ (AC straumur) eða A- (Jafnstraumur) staða.
2. Opnaðu clamp kjálkarnir með því að ýta á kveikjuna.
3. Lokið aðeins einum leiðara rafrásarinnar innan kjálkanna. Gangið úr skugga um að kjálkarnir séu alveg lokaðir.
4. Read the current value on the display. For DC current, observe the polarity.

5.3 AC/DC Voltage Mæling

1. Tengdu svörtu prófunarleiðsluna við COM flugstöð og rauða prófunarleiðslan að VΩHz flugstöð.
