Product Overview
The TH2810D is a benchtop LCR meter for the precision measurement of passive components — inductors, capacitors and resistors. It measures two components of complex impedance in a single measurement cycle, displaying a primary parameter (L, C, R or |Z|) together with a secondary parameter (D or Q) on a large-character LCD. Basic accuracy is 0.1%.
Four test frequencies (100 Hz, 120 Hz, 1 kHz, 10 kHz), three test signal levels (0.1 / 0.3 / 1.0 Vrms) and two source output impedances (30 Ω / 100 Ω) let you match the measurement conditions used by other industry-standard instruments, which is important for core inductors and other current-sensitive parts. Open and short correction data is stored in non-volatile memory for every combination of level, frequency and source impedance.
A built-in comparator sorts devices into up to four bins (P1, P2, P3, NG) plus an AUX bin, using three pairs of primary-parameter limits and one pair of secondary-parameter limits. Combined with the opto-isolated Handler interface (external trigger in; /P1, /P2, /P3, /AUX, /NG, /IDX and /EOM out), the TH2810D drops straight into an automated component-sorting line. The RS-232C port accepts SCPI commands so every front-panel function can be driven from a PC and measurement data collected for logging and analysis.
