Specification callouts to check before you order

When ordering special function testers online, look for these key specs to match your use case:

Compare these specs side-by-side using the product comparison tools on our Shop by Brand page to see which testers match your application and supported accessories.

Quick compatibility checklist

• Confirm probe tips are suitable for the package sizes you test (SMD vs through-hole).
• Ensure power/voltage ranges cover the devices under test.
• Check whether the tester needs special batteries or adapters-buy bundles if needed.

If you need guidance, our branches provide hands-on advice - see branch locations and trading hours on the Branches & Trading Hours page so you can collect the same day when stock is available in Samrand or Pretoria.

Selecting the right tester: practical examples and quick calculations

Here are common scenarios and how to pick a tester when you order special function testers online:

Example 1 - Student lab continuity and diode checks

For classroom use choose a tester with audible continuity, diode test mode and a clear display. Prioritise robustness and replaceable probes so units last through semester use. Consider a bundle that includes spare fuses and batteries to reduce downtime.

Example 2 - Technician checking electrolytic capacitors and ESR

Select a tester with ESR measurement and low-frequency ripple capabilities. Check the minimum capacitance and ESR resolution on the spec table before ordering. A lightweight bench tester with an easily readable numeric display speeds up fault-finding on power supplies.

Basic formulas and wiring diagram

Use Ohm's law for quick sanity checks when using resistance/continuity modes: V = I × R (Voltage equals Current times Resistance). When measuring power dissipation on a resistor use P = V × I or P = I squared × R.

Simple continuity probe wiring (ASCII):
  +-----------+    probe     +-----------+
  | Tester    |----/\/\/-----| Component |
  | (beeper)  |              | under test|
  +-----------+              +-----------+
