Current clamps

Foam tool tray comprising of one space for the TA018 20 / 60 A DC (low amps) current clamp, and one universal space for the TA167, TA189 or TA234.

Our two most popular current clamps pre-loaded in a Pico foam tray.

This option combines the TA018 20A / 60 A and TA167 2000 A clamps in one bundle, along with a protective storage tray.

Our two low amps current clamps pre-loaded in a Pico foam tray.

This option combines the TA018 20A / 60 A and TA234 30 A clamps in one bundle, along with a protective storage tray.

The TA234 probe is a 30 A current clamp. The extended measuring jaws allow measurement in a confined space. When measuring DC, a simple thumbwheel on the probe allows zero adjustment.

This current clamp is ideally suited for use with PicoScope oscilloscopes and features additional screening to reduce noise pickup.

The TA019 current clamp is ideal for use with a PicoScope automotive oscilloscope to display starter current waveforms, charging currents and for performing quick compression tests.

The current clamp can measure up to 600 A (AC or DC). In use there is no need to break into the circuit or disturb the isolation as the opening jaws simply clamp around the current carrying conductor. No electrical contact is required.

These current clamps have been designed for use with PicoScope oscilloscopes and feature additional screening to reduce noise pickup.

The TA018 current clamp is ideal for use with PicoScope automotive oscilloscopes for measuring currents between 10 mA and 60 A. This enables the PicoScope to display current waveforms for fuel injectors and fuel pumps.

The current clamp has two calibration settings, set by a slider switch on the handle of the probe.

  1. 1 mV/10 mA (100 mV = 1 A)

    — use this for testing currents up to 20 A.
  2. 1 mV/100 mA (10 mV = 1 A)

    — use this for testing current up to 60 A.

In use there is no need to break into the circuit or disturb the isolation as the opening jaws simply clamp around the current carrying conductor. No electrical contact is required.

These current clamps have been designed for use with PicoScope oscilloscopes and feature additional screening to reduce noise pickup.

The 200 A / 2000 A current clamp allows you to measure up to 2000 amps without cutting, or disconnecting or stripping wires. Simply clamp the jaws around the cable to be tested and plug the clamp into your PicoScope.

Before the launch of this probe we recommended the TA019 (600 A) for working on the starting and charging systems of petrol passenger cars and the PP253 (2000 A) clamp for high compression diesel engines. The TA167 (200 A / 2000 A) covers both these applications in one probe with improved range and sensitivity, lower noise and faster response.

The TA167 features a 200 A mode for better performance at lower currents and has an increased jaw size. It also features an auto power-down facility to save battery life when not in use (this feature can be disabled for battery drain / shutdown current testing).
