How do I choose between a bench multimeter and a handheld multimeter?

Choose based on use case: bench multimeters offer higher accuracy, better resolution, data logging and stable power for lab work, while handheld units prioritise portability, ruggedness and battery operation for field tasks. Compare specifications such as accuracy (ppm or %), input impedance, range coverage, sample/update rate and safety (CAT) ratings on the datasheet before buying.

Are Communica test instruments supplied calibrated or with calibration options?

Calibration status varies by product and manufacturer — check the individual product page or datasheet for supplied calibration information. If you require local calibration or a traceable certificate, contact Communica sales for recommended local calibration services and lead-time information.

What probes and accessories do I need for measuring high-frequency signals with an oscilloscope?

Use probes with bandwidth ratings equal to or greater than the oscilloscope bandwidth (typically 3–5× the highest signal frequency), low capacitance and proper impedance (e.g., 1 M? for passive, 50 ? for high-speed). Also use properly compensated probes, short ground leads or grounding accessories, and coaxial cables or differential probes for high-speed or floating measurements to reduce noise and ringing.

What safety checks should I perform before measuring mains or high-voltage circuits?

Verify the instrument and probe voltage/CAT ratings on the product label or datasheet and use leads, probes and fuses rated for the expected voltages and fault conditions. Work with the circuit de-energised when possible, use appropriate PPE and isolation techniques, and ensure a competent person supervises measurements on hazardous systems.

How can I check stock, collect orders from a branch, and get a VAT invoice for institutional purchases?

Check stock and estimated lead times on the product page or contact Communica sales for bulk or education enquiries; branches include Samrand (head office), Pretoria CBD and Cape Town with additional sub-distributors. You can select branch collection at checkout or arrange collection with sales, and request a VAT invoice at purchase or on collection by providing the required business or institutional details.

Why choose a clamp multimeter now

For makers, students and technicians in South Africa, a clamp multimeter is the quickest way to measure live currents without breaking a circuit. The right meter saves troubleshooting time, protects test equipment, and reduces shop downtime. Communica stocks a wide range of meters and accessories with local collection from Samrand, Pretoria CBD and Cape Town - so you can avoid long import lead times and get VAT invoices for procurement or institution use.

What you pay for: cost drivers and practical value

Price reflects capability. Lower-cost clamps cover bulk current checks and continuity; mid-range units add True RMS, higher accuracy, and basic logging; professional meters include record/playback, CAT safety ratings, and Bluetooth connectivity for data export. Consider spend as an investment in diagnostic speed - a well-specified clamp pays back in faster fault isolation on labs and production lines.

Jaw size - determines which conductors or cable bundles you can measure.
True RMS - required for accurate readings on non-sinusoidal loads (inverters, SMPS).
Accuracy & range - important if you log results for lab reports or acceptance tests.

Quick calculations and a wiring diagram

Basic check: use Ohm’s law to estimate expected current when validating a supply or motor during commissioning.

Formula (for DC or RMS values): I = P / V where P is power in watts and V is voltage in volts. Example: a 600 W heater on 230 V draws ~2.61 A (I = 600 / 230).

Basic ASCII wiring to clamp around one conductor (do not clamp around entire cable bundle for phase current):

  Mains Supply  Live  -----|\         /|----- To Load             | >---[CLAMP]  |  Neutral ---|/         \|----- To Load

Clamp the jaw around the single phase conductor as shown - clamping both live and neutral cancels readings. For three-phase feeders, measure individual conductors or use a multi-conductor CT/transformer rated for larger jaws.

Accessories that matter - add-ons to budget for

Cable adaptors, extended jaw kits, magnetic pickup probes, temperature probes, and Bluetooth adapters convert a basic clamp into a more versatile diagnostic tool. Communica's accessories and brands overview helps match add-ons to meter models; browse by brand and category at Shop by Brand or explore collections at Collections.

Buying locally - stock, lead times and procurement benefits

Buying from Communica reduces uncertainty in delivery and paperwork. Our Samrand warehouse plus branches in Pretoria and Cape Town enable same-day collection for many items and straightforward VAT invoicing for institutional purchases. Check branch stock and opening hours at Branches & Trading Hours to avoid delays or confirm a collection window.

Handling objections - is it worth paying more?

If you only need spot checks on resistive loads, entry clamps are cost-effective. For electrical engineering students, labs and technicians working with inverters, variable-speed drives or mixed loads, spend on True RMS and wider jaw apertures. Higher-end meters add traceable logging - valuable for formal test reports or acceptance logs.

Concern about calibration? Opt for meters with easy return-for-cal calibration paths and ask sales for calibration options.
Worried about wrong accessory fit? Communica staff can advise compatible probes and adapters by model - browse compatible accessories in the product listing or request a quote.

Compatibility guidance and bundles

Match jaw size to the largest conductor you will test. For motor/three-phase work, consider a meter with a 55-80 mm jaw or a clamp with an external CT for busbars. To streamline procurement, choose bundled kits that include test leads, a soft carry case and a temperature probe - these bundles reduce risk of missing parts in the field.
