## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=FIT0778:1` (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/FIT0778:1.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

This handheld signal generator is a versatile tool that can be used for various tasks such as debugging motor rotation, controlling light brightness, and testing external modulation signal source hardware. It has two power supply methods, three adjustment modes, and a 4-digit highlight digital tube that displays data.

The device has the capability of current output, positive and negative voltage output, and a linear output with an accuracy level of 0.05V that can be calibrated. It is fully compatible with 2, 3, and 4-wire systems and comes with output short-circuit protection and power reverse connection protection mechanisms. Videos linked below showcase the product's accuracy and output capabilities, making it a valuable tool for anyone needing a reliable source of voltage and current signals.

**Note: The manufacturer of this product makes it in two versions. One including a LiPo battery, the other not. Both have a switch on the bottom for the battery. We stock the version without the battery. If you feel capable, you can open it up and solder in [a suitable battery.](https://core-electronics.com.au/polymer-lithium-ion-battery-1000mah-38458.html)**
