## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=018-05-VAM-100V10A-BL: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/018-05-VAM-100V10A-BL: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

An all in one solution for monitoring voltage and current.

**Features:**

- Operating voltage:DC 4.5 ~ 30V
- Measure voltage: DC 0 ~ 100V
- Minimum resolution(V): 0.1V
- Measure current :10A (measure directly, built-in shunt)
- Minimum resolution(A): 0.01A
- Operating current: <20mA
- Display: three 0.28" LED digital tube
- Display color: Red and Blue (two-color display)
- Dimensions: 48 x 29 x 21mm
- Mounting cutout: 45.5 x 26.5mm
- Refresh rate: about 500mS / times
- Measure accuracy: 1% (± 1 digit)
- Operating temperature: -10 to 65° c
- Operating Humidity: 10 to 80% (non-condensing)
- Working pressure: 80 to 106 kPa
 
**Wiring:**

- Black line (thick): Current Sense - (Shunt Resistor)
- Red line (thick): Current Sense + (Shunt Resistor)
- Black line (thin): COM, common measuring
- Red line (thin): Power IN+, (4.5-30V)
- Yellow line (thin): Voltage Sense In+ (0-100V)
- (Please refer to the wiring diagrams for more details)
 
**Notice:**

- The voltage between the thin red and thick black lines must be within DC 4.5-30V
- Both Black wires are on a common ground.
- The ammeter can only be connected to the negative of the device under test
- Voltage can be calibrated using the Potentiometer
- Current accuracy can be up to ±0.1A
- 10A and below ammeter (this model) has a built-in shunt and does not require external shunt
- If long-term full load working continuously exceeds 5A it is recommended that the measurement side of the leads are directly soldered to the socket
- When the black thick line is not connected it is recommended to use insulating tape around the exposed part of the wire to prevent short circuits
- If used as a voltmeter alone it is recommended that the yellow line and the black line were connected together to prevent the ammeter digital flashing
