6 Measurement Connections
4 front panel BNC guarded connectors with the screens at ground potential.
Terminals withstand connection of charged capacitor up to 5V, either polarity.
7 Measurement Accuracy
The accuracy statements given apply when the instrument is used under the following
measurement conditions.
Slow speed, 4-terminal measurement. The instrument must have warmed up for at least 30
minutes at a steady ambient temperature of between 18°C and 28°C. The instrument must have
been trimmed with its measuring leads and fixture at the measurement frequency.
Except on the highest and lowest hardware measurement ranges, the accuracy chart also apply
to medium speed. For maximum and fast speed, the figure must be doubled.
Accuracy chart define the measurement ranges available, at specified accuracies, over the
available frequency band. All curves assume that Slow measurement speed is used, that the
LCR meter has been trimmed at the frequency and level used for measurements, factory
calibration are valid and that the component under test is pure.
