Analog Ohmic Measurement Device

Quick Answer: An Analog Ohmic Measurement Device is an analog ohmmeter that measures the resistance of a single, isolated component or circuit path and shows the value on a moving-pointer, graduated scale rather than a digital number. LabEquip supplies this instrument for supervised resistance-testing and circuit-analysis exercises. Exact range settings, scale multiplier, battery specification and accuracy are model-dependent, so please confirm these with our sales team before ordering.

Description

Like other analog ohmmeters, this instrument works by passing a small test current from an internal battery through the component under test and deflecting a pointer according to the resulting current, which is calibrated against a resistance scale. Before taking a reading, an analog ohmmeter typically needs its range selected and its pointer “zero-adjusted” with the probes shorted together, since the internal battery’s condition affects the zero point. The component being tested must be isolated from any other circuit or power source, otherwise the reading will be inaccurate or the meter may be damaged.

This is an analog instrument, so its scale must be read visually rather than as a direct digital number — this is a genuine difference from any digital ohmmeter LabEquip may also stock. If your teaching activity specifically calls for either an analog pointer reading or a digital numeric readout, let our sales team know so we can confirm the right instrument for you.

Specifications

Care & Maintenance

• Always isolate the component from any circuit or power source before measuring its resistance.
• Re-zero the meter each time you change range or the reading looks unreliable.
• Replace the internal battery when the meter can no longer be zeroed correctly.
• Keep the probes and terminals clean to avoid contact-resistance errors.
• Store the meter in a dry case, away from vibration, when not in use.

Frequently Asked Questions

What does an Analog Ohmic Measurement Device measure?

It measures the electrical resistance of a single, isolated component or circuit path, shown on a moving-pointer analog scale.

Why do I need to zero-adjust an analog ohmmeter before use?

The internal battery’s condition affects where the pointer sits at zero resistance, so the meter is zeroed with the probes shorted together before each measurement or range change.

Can I measure resistance while the component is still connected in a circuit?

No, the component being tested should be isolated from any other circuit or power source; testing it in-circuit can give an inaccurate reading or damage the meter.

How is this different from a digital ohmmeter?

This is an analog instrument with a moving pointer and graduated scale, while a digital ohmmeter shows the value as a direct numeric readout. Both measure resistance, but they are read differently.

What range and battery does this meter use?

Range settings, scale multipliers and battery requirements vary by model. Please confirm these details with our sales team before ordering.

Is this suitable for classroom resistance-testing exercises?

Yes, it is intended for supervised resistance-testing and circuit-analysis activities in physics and electronics teaching.
