Speedy accuracy from LCR meters
The SRS SR715/720 family of LCR meters quickly and accurately measures passive components with as little as 0.05% error
The SRS SR715/720 family of LCR meters, now available in the UK from TTi (Thurlby Thandar Instruments), quickly and accurately measures passive components with as little as 0.05% error. The low-cost instruments are easy to set up, adjust and calibrate, making them ideally suited for applications such as incoming inspection, quality control, automated test and general benchtop use.

Logger takes temperatures and voltages
The Yokogawa Datum Y is a compact data logger for remote and portable applications
Five different test frequencies of 100Hz, 120Hz, 1kHz, 10kHz and 100kHz (SR720 only), three preset voltage levels, internal and external capacitor biasing and three different measurement speeds allow unmatched flexibility to create the correct test environment.
The convenient auto-measure mode simplifies measuring unknown parts by automatically calculating the best part model and range for any component.
Capacitor measurements use either the internal 2.0V DC bias or an external DC source of up to 40V.

Dual-display multimeters have graphical edge
The Fluke 8845A and 8846A are high-precision dual-display multimeters offering a wide range of functions for benchtop or system applications
Stray impedances are removed from measurements with a simple, fast null calibration procedure.
The built-in Kelvin fixture handles radial-lead components, and adaptors are included for axial components.
Optional fixtures include SMD tweezers, Kelvin clips and BNC adapters.
Built-in binning sorts components into overlapping or sequential bins.
Up to nine complete instrument configurations may be saved to non-volatile memory for quick setup.
For easy integration with computerised test environments, an RS232 interface is standard, with optional IEEE488 and handler interfaces.
Measurement modes are auto, R + Q, L + Q, C + D and C + R, with series or parallel equivalent circuits.
The display indicates the parameter value, deviation, percentage deviation or bin number.
Deviation and percentage deviation are calculated relative to a stored value.
Measurement ranges are 0.0001ohm to 2Gohm for resistance, 0.0001uH to 99999H for inductance and 0.0001pF to 99999uF for capacitance.
Q can be measured between 0.00001 and 50 and D between 0.00001 and 10.
Basic accuracy is 0.20% for the SR715 and 0.05% for the SR720.
Prices start at GBP 1305.
