AD2817C Operation Manual

2.6 Function

2.3.1 Correction

Open correction:
to eliminate measurement errors due to parasitic stray admittance (C,
G) of the test fixture.
Short correction:
to eliminate measurement errors due to parasitic residual impedances
(L, R) of the test fixture.
Cable length calibration:
0m: to measure with terminal fixture;
1m: to measure with 1m cable of TH26009, TH26011
CUST: to calibrate with cable of required length. And the shipped instrument hasn't been
performed calibration.
Correction function can be turned off.

2.3.2 Comparator

The instrument can perform multi-bin sorting and support signal output of HANDLER
interface.
BIN1 to BIN3:
Both primary and secondary measurement parameters are within limits.
OUT BIN:
Primary parameter is not within limits. Or primary parameter is within limits,
secondary parameter is not within limits, and AUX bin is off.
AUX BIN:
Primary parameter is within limits, but whose secondary parameter
measurement result is not within limits.
Sorting mode:
ABS (absolute deviation):
value is compared with bin limit.
PER (percentage deviation):
nominal value is compared with bin limit.

2.3.3 Parameter display

Direct:
The actual measured values will be displayed.
:
Absolute devation between measured result and nominal value is displayed.
%:
Percentage deviation between measured result and nominal value is displayed.

2.3.4 Transformer parameter measurement

AD2817C has the function of measuring basic parameters of single transformer through
2-wire mode. And special test fixture should be used at the time of transformer
measurement.
