Faster measurements put LCR meters on the line

An ASM product story

The latest versions of the Hioki 3522 and 3532 LCR instruments have been enhanced to work at four times the speed of their predecessors, making them ideal for both laboratory and production line use.

The latest versions of the Hioki 3522 and 3532 LCR instruments have been enhanced to work at four times the speed of their predecessors, making them ideal for both laboratory and production line use.

The 3522-50 and 3532-50 are packed with easy-to-use functions and enable simulation of test conditions that are close to the component operating environment.

With a minimum measurement time of 5ms, the instrument provides for improved production line efficiency.

Interactive touch screen operation allows the user to touch the relevant item on the screen and the possible settings appear in sequence.

The neat and simple front panel eliminates all keyswitches for a clutter-free design.

The measurement frequency can be freely set between DC and 100kHz (3522-50) or between 42Hz and 5MHz (3532-50) with a full five-digit measurement resolution and +/-0.08% basic measurement accuracy.

The meters provide a capability for measuring 14 different parameters, and selected parameters can be captured by a PC.

In addition to normal open-loop signal generation, these units provide for voltage/current dependent evaluation in constant voltage and constant current modes.

The signal levels can be set over wide ranges from 10mV to 5V RMS and from 10uA to 100mA.

Measurement frequency, measurement signal level and other measurement conditions can be changed while monitoring the measurement results, enabling effective trial measurements and setting of evaluation conditions.

Up to 30 sets of measurement conditions, including comparator values, provide rapid response to constantly changing components on flexible production lines.

With multiple measurement conditions in memory, up to five different measurements can be made sequentially.

The comparator function lets a single unit provide the logical and result for this sequence of tests.

Any four of the 14 parameters can be chosen for simultaneous measurement and display.

Up to four parameters can be zoomed for easy observation of measurement values in a production line and other situations where the unit is required to be read from a distance.

With the optional 9442 printer, measurement values, comparator results and screen printouts can be obtained.

Using the optional 9268/9269 DC bias unit, voltage and current bias measurements are made simple.

The maximum applied bias is +/-40V DC, depending on measurement conditions.

An external I/O interface can input trigger signals and provides a key on/off lock function as well as remote control loading of the measurement conditions.

Output signals include comparator results and measurement completed signals for complete line automation.

Using the optional RS232/GPIB interface, all 50 functions other than power on/off can be controlled from a PC.

If required, measurement data can be displayed graphically using standard spreadsheet software.
