4. Setup
4.1 Power Probe III Connection
To power the Power Probe III, connect its power leads to a 12V or 24V vehicle battery. The red lead connects to the positive (+) terminal, and the black lead connects to the negative (-) terminal.

4.2 PPDMM Battery Installation
The PPDMM requires three AAA batteries for operation. Open the battery compartment on the back of the multimeter and insert the batteries according to the polarity indicators. Securely close the compartment.
5. Operating Instructions
5.1 Using the Power Probe III
The Power Probe III allows for quick testing of electrical circuits by providing power or ground to components. Once connected to a vehicle battery, the tool's tip can be used to probe circuits. The display will show voltage readings.
- Voltage Testing: Touch the probe tip to the circuit point. The LCD will display the voltage.
- Power/Ground Supply: Use the rocker switch to apply battery voltage (forward) or ground (backward) to a component for functional testing. Caution: Ensure the component can handle direct battery voltage or ground before applying.
- Continuity Testing: With the tool powered, touch the probe tip to a ground source. If the circuit is continuous, the tool will indicate continuity.

5.2 Using the PPDMM Digital Multimeter
The PPDMM is a versatile multimeter for precise measurements of voltage, resistance, current, and temperature.

- Voltage Measurement (AC/DC):
- Turn the rotary dial to the desired ACV or DCV range.
- Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.
- Touch the probe tips to the circuit points to measure voltage.
- Resistance Measurement:
- Turn the rotary dial to the "Ω" (Ohms) range.
- Connect the red test lead to the "VΩmA" jack and the black test lead to the "COM" jack.
- Touch the probe tips to the component to measure resistance. Ensure the circuit is de-energized.
- Current Measurement:
- Turn the rotary dial to the "A" (Amps) range.
- Connect the red test lead to the "10A" or "mA" jack (depending on expected current) and the black test lead to the "COM" jack.
- Break the circuit and connect the multimeter in series with the circuit to measure current.
- Temperature Measurement:
- Turn the rotary dial to the "°C/°F" range.
- Connect the K-Type temperature probe to the designated jacks.
- Place the tip of the temperature probe on the surface or in the medium to be measured.

6. Maintenance
6.1 Cleaning
Wipe the tools with a damp cloth. Do not use abrasive cleaners or solvents. Ensure the tools are dry before storage.
6.2 Battery Replacement
Replace the AAA batteries in the PPDMM when the low battery indicator appears on the display. For the Power Probe III, ensure the vehicle battery connection is secure and providing adequate power.
6.3 Fuse Replacement
If the Power Probe III or PPDMM ceases to function due to an overload, check and replace the internal fuses as per the specific instructions in their individual manuals. Always use fuses of the correct rating.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Power Probe III does not power on. | Incorrect battery connection; vehicle battery discharged; blown fuse. | Verify red lead to positive, black lead to negative. Check vehicle battery voltage. Inspect and replace fuse if necessary. |
| PPDMM display is blank or dim. | Low or dead batteries; incorrect battery installation. | Replace AAA batteries. Ensure batteries are inserted with correct polarity. |
| Inaccurate readings on PPDMM. | Incorrect measurement range selected; poor test lead connection; damaged test leads. | Select appropriate range. Ensure test leads are securely connected. Inspect test leads for damage and replace if needed. |
| Power Probe III does not supply power/ground. | Blown internal fuse; insufficient power from vehicle battery. | Check and replace the internal fuse. Ensure the vehicle battery is fully charged. |
