C. DC Current Measurement (mA or µA)
- Critical warning: Connect in series with the load. Never parallel across a voltage source.
- For current > 100mA up to 500mA: Move red lead to 500mA jack.
- Set selector to the appropriate mA range.
- Break the circuit and insert the meter in series.
3.2. Controls and Indications (Page 2 – Illustrated Diagram)
- Mechanical Zero Adjust Screw: Small plastic screw under the meter needle (to zero the needle before measurements).
- Range Selector Knob: Rotary switch (positions: OFF, DCV, ACV, mA, Ω).
- Ohms Adjust (Zero Ohms) Knob: Used to zero the meter needle on the Ω scale after range changes.
- Test Lead Jacks:
- COMMON (-) – Black jack.
- POSITIVE (+) – Red jack (for most ranges).
- 500mA – Dedicated jack for high current measurements.
Step 2: Mechanical Zero Adjustment
Before any measurement, look at the meter face. Locate the small screw (usually plastic) directly below the center of the needle pivot. Use a small flathead screwdriver to turn it until the needle rests exactly on the 0 mark at the far left of the scale (for voltage/current) — not the infinity symbol.
Troubleshooting Common Problems (From the Manual)
The original user manual includes a troubleshooting section. Here are the most frequent issues and their official solutions:
| Problem | Likely Cause (per manual) | Solution |
| :--- | :--- | :--- |
| No reading on any range | Dead internal fuse (0.5A, 250V, fast-blow) | Replace fuse. Access via back cover. |
| Ohms function won't zero | Low batteries (1.5V or 9V) | Replace both batteries. |
| Needle sticks or moves sluggishly | Debris in movement or mechanical damage | Service by qualified technician only. |
| Inaccurate DC voltage readings | Worn test leads or internal calibration drift | Clean leads. For calibration, return to RadioShack (not possible now—seek vintage calibration guide). |
| AC voltage reads on DC scale | Incorrect switch setting | Ensure function switch is on ACV, not DCV. |
