Questions about this item

Should I choose the direct power or key-switch power connection?

Use direct power for always-on indication; choose key-switch power if you want the meter to turn off with the ignition.

What does the 10-bar LED display tell me while the machine is running?

Each of the 10 bars shows 10 % capacity — 1 red, 2 yellow and 7 green bars step up during charge and step down during discharge.

How does the IP65 rating limit where I can mount the meter?

IP65 protects against dust and low-pressure water jets, so the meter can be panel-mounted in exposed areas on 36 V lead-acid equipment.
