Manual Pdf - Equus 4320
Used for checking fuses, switches, and diodes.
This section is gold for those facing a "Check Engine" light and a failed smog test. The manual teaches you how to interpret:
If the manual says "Inc," that means the monitor is incomplete. The back of the manual provides a universal drive cycle procedure to force the car to re-run its tests.
Older vehicles (pre-2008) can use five different protocols (VPW, PWM, ISO, KWP2000, CAN). The Equus 4320 is an intelligent scanner—it auto-detects protocols. The manual explains what the LED lights mean:

Final Recommendation: Always attempt to retrieve the official manual from Innova’s legacy support first. If unavailable, the Innova 3320 manual is a perfect substitute. Avoid random “free PDF” sites that require registration or payment – the Equus 4320 manual is an older, freely distributable document.
The Equus 4320 is a professional-grade 10 MegOhm Digital Multimeter designed for automotive, home, and electronic diagnostics.
A digital copy of the manual is essential for understanding its safety limits and specific testing procedures, such as diode or battery health checks. 🛠️ Key Technical Specifications
Input Impedance: 10 MegOhm (safe for automotive computer circuits/ECUs). Maximum Voltage: Up to 500V DC or AC.
Protection: Overload protection up to 230 Vrms on lower ranges; utilizes a 0.315A/250V internal fuse.
Primary Functions: Measures AC/DC voltage, DC current, resistance, diodes, and continuity. ⚡ Quick-Start Testing Guide For most standard tests, follow these lead placements:
Standard Hookup: Plug the Black lead into the COM jack and the Red lead into the VΩmA jack.
DC Voltage (Batteries): Set the dial to DCV. Connect Red to positive (+) and Black to negative (-).
Resistance (Ohms): Ensure the circuit is de-energized before testing to avoid damaging the meter.
10A Current: If measuring high current, move the Red lead to the dedicated 10A jack. 🔧 Maintenance & Troubleshooting
Not Powering On: Check the 1.5V AA batteries. If the low battery icon appears, readings may become inaccurate.
No Current Reading: This usually indicates a blown fuse. Replace it only with a 0.315A/250V (5x20mm) type fuse (Bussmann GMA or similar).
Cleaning: Use a damp cloth only; avoid solvents which can degrade the plastic housing. 📥 Where to Find the Manual

Troubleshooting Like a Pro: Your Guide to the Equus 4320 Digital Multimeter
Whether you’re a weekend DIYer or a seasoned mechanic, having a reliable digital multimeter (DMM) in your toolbox is non-negotiable. One of the most popular entry-level choices is the Equus 4320
, often rebranded under the Innova line. If you've lost your physical manual or just bought a used unit, this post will walk you through the essentials found in the Equus 4320 User Manual Equus 4320
is designed specifically for automotive and household electrical testing. It’s compact, affordable, and features an easy-to-read digital display that takes the guesswork out of analog needles. Key Specs at a Glance:
Safety First: Includes overload protection and high-quality test leads.
Versatility: Measures AC/DC voltage, resistance (Ohms), and DC current.
Battery Testing: Includes a dedicated function for testing 1.5V and 9V batteries under load. Getting Started: The Basics
Before you start poking around live circuits, it’s vital to understand the layout of your device.
The Display: Shows your measurement readings and low-battery indicators.
The Selector Dial: This is the heart of the meter. You must set this to the correct range before connecting your leads. Input Jacks: COM (Black): The common (negative) ground jack.
VΩmA (Red): Used for most measurements (Voltage, Resistance, and small current).
10A (Red): Only used for measuring high-amperage DC current. How to Perform Common Tests 1. Testing a Car Battery (DC Voltage)
Set the dial to the 20V DC range. Touch the red lead to the positive terminal and the black lead to the negative. A healthy, fully charged car battery should read approximately 12.6V. 2. Checking for Continuity
Want to see if a fuse is blown or a wire is broken? Set the dial to the Resistance (Ω) or Continuity setting. Touch the leads together; you should see a reading near zero (or hear a beep if your model supports it). If it shows "1" or "OL," the circuit is open (broken). 3. Testing Household Outlets (AC Voltage)
Caution: Household current is dangerous. Set the dial to 200V or 500V AC. Carefully insert the probes into the outlet slots. You should see a reading around 110V-120V (in the US). Maintenance & Safety Tips
Lead Inspection: Always check your test leads for cracks or exposed wire before use.
Fuse Replacement: If you accidentally measure high current on the wrong setting, you might blow an internal fuse. Refer to the maintenance section of the manual for replacement instructions.
Keep it Dry: Never use the meter in wet conditions, and clean the casing with a damp cloth only—no solvents! Download the Manual
