Purpose and fit

The Blue Sea Systems 1732 Mini OLED Ammeter is a compact marine instrument for 12V or 24V DC electrical systems. It suits boat owners and installers who need real-time amperage data on a bright, waterproof, daylight-readable OLED screen. The meter mounts in a standard 1-1/8" hole for flexible placement.

Deciding specification

The meter monitors current from -100A to 100A DC with a resolution of 0.1A and an accuracy of ± 2%. It accepts positive or negative side wiring and operates on an input voltage range of 8-36V DC while drawing only 15mA. Reverse polarity protection is built in.

Bundled impact

The unit is classified as an accessory and arrives as a standalone meter. No separate shunt, wiring harness or configuration software is included, so installers must supply their own connections and mounting hardware to complete the installation.

Questions about this item

What does the 100A range tell me about the current I can actually watch on my boat?

The meter reads from -100A to 100A DC with 0.1A resolution, so you see charge and discharge currents up to that level on the OLED screen.

How does the 12V/24V nominal voltage and 8-36V input range limit where I can wire it?

It powers from any 8-36V DC source, covering both 12V and 24V nominal systems, and draws only 15mA itself.

What size hole and clearance do I need to mount the 1732 in a panel?

It fits a standard 1-1/8" cut-out; the compact case slides through from the front and secures with the supplied hardware.
