Multi-Scale Digital Ammeter

Quick Answer: A Multi-Scale Digital Ammeter is a digital-readout instrument connected in series in a circuit to display current, with “multi-scale” meaning it offers more than one selectable current range on a single unit. LabEquip can confirm the exact ranges and switching method for this model before you order.

Description

Like our other ammeters, this instrument is connected in series so the current being investigated passes through it or its approved sensing arrangement, and the digital display presents the measured value numerically. The “multi-scale” design means the same unit can cover more than one current range rather than being fixed to a single scale, which is useful where a lab or trainer needs to measure both small and larger currents without swapping instruments. Please confirm with our sales team exactly how many ranges are supported and whether switching between them is manual or automatic.

If your application needs a heavier-duty, single-range instrument instead, our Industrial Digital Ammeter is also available in the Measuring Instruments range — our sales team can help you compare the two against your current requirements.

Specifications

Care & Maintenance

• Always connect the ammeter in series, never in parallel, with the circuit under test.
• Select the appropriate current range before taking a reading, starting from the highest range if unsure.
• Do not exceed the rated current of the instrument on any range.
• Keep terminals clean, dry and free of dust and corrosion.
• Have the meter periodically checked against a reference standard if used for calibrated measurement work.

Frequently Asked Questions

What does “multi-scale” mean for this ammeter?

It means the instrument offers more than one selectable current range on a single unit, rather than being fixed to one scale. Please confirm the exact ranges with our sales team.

How many current ranges does it support?

This is model-dependent. Our sales team can confirm the exact range configuration before you order.

How is this different from the Industrial Digital Ammeter?

The Industrial Digital Ammeter is positioned as a heavier-duty, more industrial-focused instrument, while this model is described as multi-scale for flexible range coverage. Our sales team can compare both against your requirements.

Do I connect it in series or parallel?

An ammeter is always connected in series with the circuit under test, so the current to be measured flows through the instrument.

Can it be panel-mounted into a trainer or switchboard?

It is designed to be mounted into a compatible panel or trainer chassis where the cutout size and terminal arrangement match. Please confirm mounting dimensions before purchase.

Does it need an external power supply?

Many digital display meters need a separate auxiliary supply to power the display electronics, in addition to the current being measured. Confirm the supply requirement for your chosen model with our team.
