## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE10606:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE10606:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

A smart digital multimeter equipped with a high-contrast 9999-count VA colour LCD, designed for precise, everyday electronic measurements. Functioning as a quick-to-grab diagnostic tool for makers and engineers, it reliably measures AC/DC voltage, resistance, capacitance, and frequency while offering non-contact voltage (NCV) and live wire detection capabilities.

Traditional multimeters often require constant dial adjustments, which can slow down your workflow and risk blowing a fuse if the wrong range or mode is selected. The S1 solves this common pain point with an intelligent auto-measurement system that instantly identifies whether you are probing voltage, checking resistance, or testing continuity, streamlining both benchtop diagnostics and rapid field repairs.

Housed in a robust ABS plastic enclosure, this compact unit feels solid in the hand and features an internal 1000mAh lithium battery to completely eliminate the need for disposable 9V or AA cells.

### Key Features

- **Enjoy rapid, error-free diagnostics** with smart auto-measurement that instantly identifies AC/DC voltage, resistance, and continuity without requiring manual dial-switching.
- **Read measurements easily in any environment**—from dimly lit workshops to bright outdoor settings—thanks to the vibrant 9999-count dual-display VA colour screen and integrated flashlight.
- **Eliminate the hassle of swapping batteries** with the built-in 1000mAh rechargeable lithium battery, offering up to 5 hours of continuous runtime via a standard USB-C port.
- **Achieve highly accurate readings on complex AC signals** (such as PWM outputs or inverter drives) with True RMS measurement capabilities.
