Remote Control

This LCR model has the RS232C serial interface which can be used to remotely control UC2836/UC2858X . This chapter provides the information about the interface and how to use the interface.

RS232C Interface Introduction

The RS232C interface can be used to remotely control the UC2836/UC2858X. All operations from the front panel can be performed by a computer via the serial interface.

RS232C Connection

RS232C Standard now is widely used as the serial communication standard. RS232 stands for Recommend Standard number 232 and C is the latest revision of the standard.

The serial ports on most instruments use a subset of the RS-232C standard. The full RS-232C standard specifies a 25-pin “D” connector of which 22 pins are used.

 

Measurement Functions

Measurement parameters
L: inductance,  C: capacitance,  R: resistance
Z: impedance,  X: reactance
D: dissipation,  θ: phase angle,  Q: quality factor

Range

UC28xx totally has 9 ranges: 10Ω, 30Ω, 100Ω, 300Ω, 1kΩ, 3kΩ, 10kΩ, 30kΩ, 100kΩ.
Please refer to the following table for range and its corresponding measurement range.

It’s recommended to select range auto mode mostly, to avoid incorrect measurement caused by wrong selection of range . But in some special cases, range should be held, such as measurement of the same type in batch and sorting test, in order to improve efficiency, speed and stability. Inductance’s bias test should be performed at held range.

Trigger mode

Internal:  When the trigger mode is set to internal trigger mode, the instrument continuously repeats measurements.
External:  When the trigger mode is set to external, the instrument performs a single measurement every time a low-to-high transition TTL level signal is applied to the Handler interface on the rear panel.
Manual:  When the trigger mode is set to manual trigger mode, the instrument performs a single measurement every time when TRIGGER key on the front panel is pressed.

Measurement delay
Delay time: time from trigger to start. 0 to 60s are programmable with a resolution of 1ms.

Measurement speed
Measurement speed can be affected by test frequency, integral time, value of component, display mode, range mode, average times and comparator. And the following parameters are evaluated at the status of frequency of 10kHz, range hold, comparator off, no communication interface, which is possibly maximum values:

FAST: 30meas/sec (f≧1kHz)
MED: 10meas/sec (f≧1kHz)
SLOW: 3meas/sec (f≧1kHz)

At the frequency of being lower than 1kHz, measurement speed will slow down. And transformer parameter measurement at the same conditions, especially resistance measurement, will have lower speed.
