Genrad 1689 Digibridge
Precision RLC Bridge
Component Tester / LCR Meter
This instrument is the bench mark in LCR meters for precision (.02%
basic accuracy) and speed (Up to 30 readings per second). The 1689
keyboard is simple to operate using the prompt sheet. Included are the Prompt Sheet,
set of Genrad Radial Clips and the Operation & Service Manual. This unit has
been professionally referbished and is in near Mint Condition. It is in excellent
physical and electrical condition.
It is seen in the photo with an ESI 500 Ohm percision resistor.
Programmable RCL Digibridge
The 1689 automatically measures R L C D & Q it
displays capacitance from .00001 pF to 99999 microF, resistance from .00001
ohm to 99999 Kohms, and inductance from .00001 mH to 99999 H with .02% accuracy,
D & Q from .0001 to 9999. External
Bias Voltages to 60 vdc maybe applied from a rear panel input. An Internal
bias of 2 volts may be applied to capacitors by using the INT BIAS function.
Test Voltages from 5 mV to 1.275 V in 5 mV steps are available. Over 500
test frequencies may be selected from the range of 12 Hz to 100 kHz.
