Measurement Functions
5.1.1
Measurement Parameters and Notations
R: resistance
V: DC voltage
Z: impedance X: reactance
L: inductance Q: quality factor
: phase angle (deg degree)
r: phase angle (rad radian)
5.1.2
Measurement Groups
ST2523 has nine measurement groups: R, R-V, V, R-Q, L-Q, L-R, R-X, Z-
, and Z-r.
5.1.3
Mathematical Operations
Mathematical operations on ST2523 are options to display absolute value deviation (ΔABS) or percentage
deviation (Δ%) between a measurement value and a programmable nominal value.
5.1.4
Range
Double-range bin for resistance and DC voltage, Mode: AUTO, MANU (HOLD, UP, DOWN)
5.1.5
Trigger
Internal, manual, external, bus
Internal: Continuously test a DUT and then output and display the result.
Manual: Press the “TRIGGER” button on the panel, the instrument will test a DUT once and display
the result. This mode keeps in waiting mode when it is not used.
External: Test a DUT once and display the result when the instrument receives an external “start up”
signal from the footswitch of HANDLER interface or EXT HOLD interface on the rear panel.
BUS: Send the measurement result to an upper computer through the communication interface and the
instrument will not display the result.
5.1.6
Averaging
Range from 1 to 255 individual measurements, programmable
