Page 5: Safety Precautions
• Do not attempt to measure any components in-circuit when your circuit is alive • or active. To avoid possible damage to TDI LCR Smart Tweezers or to the equipment under test, follow these guidelines: • Disconnect circuit power supply and discharge all high-voltage capacitors before •... -
Page 6: Getting Started
MENU STRUCTURE: Covers menu structure, system settings and features. OVERVIEW TDI LCR Smart Tweezers (ST) is a portable impedance measuring device. ST is capable of measuring resistance, capacitance or inductance over a range of more than 8 orders of magnitude. The device has a basic accuracy better than 0.2% (resistance) and operates at four test frequencies. - Page 7 TDI International, Inc. The Technical Source! HOW IT WORKS ST evaluates impedance of a component by measuring the voltage across the com- ponent and current through it. The complex ratio of voltage to current is equal to the complex impedance. The unit’s processor calculates various parameters that are dis- played i.e.
- Page 8 TDI International, Inc. The Technical Source! The output voltage is applied to the device under test through the source of imped- ance. The voltage across the device is always less than or equal to the output voltage. Source impedance values are 62.5...

Page 9: Controls
TDI International, Inc. The Technical Source! CONTROLS The Navigation Controller The controller is used to select a function or to change a setting of Smart Tweezers. The controller can be moved (rocked) in 4 directions (UP, DOWN, LEFT, RIGHT). Se- lection is performed by pressing along the vertical axis (PRESS). -
Page 10: Power On
TDI International, Inc. The Technical Source! POWER ON POWER-ON - To Turn the Smart Tweezers ON, press the navigation controller. Note: Once powered on, the unit will perform the last selected function. POWER-OFF - ST powers off automatically if neither a measurement is performed or the navigation controller is operated for approximately 30 seconds (default value). - Page 11 TDI International, Inc. The Technical Source! PRIMARY DISPLAY: The Primary Display is located in the middle of the screen and uses the largest font. It shows the dominant impedance parameter reading typically with 5 digits displayed. SECONDARY DISPLAY: The Secondary Display is located just above the Primary Display.

It checks whether the measured com- ponent is within preset tolerance from the reference component. The tolerance ranges available are 1%, 5%, 10% and 20% To preset a tolerance range: •...
- Page 21 TDI International, Inc. The Technical Source! One common application is to increase the accuracy of a small resistance measure- ment by storing (nulling) the test resistance (test leads shorted). Obtaining the leads offset (nulling) is also particularly important prior to making small capacitance measurements (test leads open).
- Page 22 TDI International, Inc. The Technical Source! During measurements an asterisk will appear beside the test mode indicator for which the offset has been stored indicating relative measurement. To reset (set to zero) the stored offset for a particular test mode: •...

TDI International, Inc. The Technical Source! Optimal Test Frequency <10000pF 10kHz 1kHz 10001pF-1 There is some small capacitance offset due to capacitance of the tips. The offset de- pends on the distance between the tips (i.e. measured component size). The offset value should be used in calculation of the actual capacitance. -
