REMOTE COMMUNICATION
To USB port of
This instrument has a bi-directional (full duplex) communication
capability. This function will assist user to record and keep data easily.The
protocol is provided bySCPI commands (Standard Commands for
Programmable Instruments). You can simplyuse your familiar language to
design what application software you want. All commands are combined by
ASCII character, non-hexadecimal, which ismuch user friendlyproviding. Just
configure the measuring range, and then get the measuring value. The detail
SCPI for remote operation is accompanied with another file on this CD-ROM.
Please refer to.
The AK80B accessory includes an optical USB-RS232 cable and a CDROM for PC applicationsoftware (included with 830B and optional formodel
890B).
Please refer following procedures if you want to communicate with
personal computer:
1. Setup the communication parameters for the meter and the personal
computer you used. The meter is default to (9600, n, 8, 1).
2. Be sure thatthe driver for USB and RS-232 transfer has been installed on
your computer.
3. Fixes optic side of cable to communication port of meter,Be sure the text

CAPACITANCE MEASUREMENT
Cau
tion
Toavoid possible damage to the meter or the equipment under
test, disconnect circuit power anddischarge the capacitor
before measuringcapacitance.
Capacitance is the abilityof a component to store an electrical charge.The
unit of capacitance is the farad (F). Most capacitors are within the range for
nanofarad (nF) to microfarad (μF).The metermeasures capacitance by
charging the capacitor with a known current, measuring the resulting time of
charging period, and then calculating the capacitance. The larger capacitors
will take longer time to charge. Thesign of “C” flashing means charging
capacitor. To improve the measurementaccuracyof small value capacitance,
press RELwith the alligator clip leads open tosubtract the residual
capacitance of the meter and leads.
Measuringtip: For measuring the capacitancemore than 1000μF,you can
discharge capacitor first andselect suitable range to measure it.That will
speed up measuring time for get the correct value.
1. Turn on the meter.
2. To keep the open whatever you usesockets, alligator clip leads or SMD
tweezers to test capacitance. And then press REL to subtract the residual
capacitance of the meter and leads
3. Insertthe leads ofcapacitor into "+" and "-" input sockets, respectively.
4. Be sure the polarityfor capacitor.
5. Remove your hands from capacitor.
6. Read the display.
