Never leave the red lead in the mA jack when trying to measure voltage. You will blow the internal fuse (often a 200mA/250V fast-blow glass fuse).
Break the circuit and connect the meter in series so the current flows through the device.
If your specific 22-806 is rated for 600V (check the label), yes. But exercise extreme caution. The probe insulation and CAT rating are low. radio shack digital multimeter 22-806 manual
| Label | Function | |-------|----------| | | Power off | | DCV (200mV – 600V) | Measures DC voltage (batteries, car adapters) | | ACV (200V – 600V) | Measures AC voltage (wall outlets, appliances) | | DCA (200µA – 200mA) | Measures DC current (small loads only) | | Ω (200Ω – 2000kΩ) | Measures resistance | | Diode / Continuity | Tests diodes or checks for short circuits (buzzer sounds) | | hFE | Tests transistor gain (NPN/PNP) |
This article serves as a comprehensive resource for the . We will explore the features of the device, explain how to interpret the symbols, provide step-by-step operating instructions, and offer troubleshooting tips to keep your unit functioning for years to come. Never leave the red lead in the mA
The is a vintage auto-ranging digital multimeter designed for home, lab, and industrial inspections . It features a handheld form factor with basic electrical measurement capabilities and a distinctive retro design. Key Features & Specifications
| Problem | Likely Cause | |---------|---------------| | Display blank | Dead batteries or dial not turned from OFF | | OL or 1 in voltage mode | Over-range (select higher range if manual) | | No continuity beep | Broken test lead or open circuit | | Inaccurate readings | Low battery (replace both AAA cells) | If your specific 22-806 is rated for 600V
Denoted by a "V" with solid and dashed lines. This measures Direct Current voltage, found in batteries, car electronics, and logic boards.
