... or ... make up a tiny PCB with a dedicated ISense amp ie INA286 etc there are literally 100s. Use a fixed, say x100 gain, and a shunt to give 1-10mV MAX
That will get you 100mV > 1V DC op, where you use a Voltmeter. If you already have a current meter, many / most can be converted to Volts by removing
the internal shunt. Worst case, it's not a huge cost. In higher current scenarios, I've simply picked 2 points on the output leads, and calibrated to that.
The temp accuracy is a bit drifty at high currents, but you're only doing 1A max.
Make up your own escutcheon with your own symbols etc .. always liked doing those.
