Setting COMPARE = ON-VAL will display the primary and secondary readings in addition to a

GO (PASS). A LO reading is lower than the set nominal value and a HI reading is higher than

the set nominal value.

Setting COMPARE = ON-Δ will display the difference between the measured value and the set

nominal value. A GO, LO, or HI judgment is also displayed.

Setting COMPARE = ON-Δ% will display the percent difference between the measured value

and the set nominal value. A GO, LO, or HI judgment is also displayed.

2.4.10 BIAS CURRENT

The 1730T instrument can be connected to a 1320 Bias Current Source to generate up to 100A of

external DC bias current to the device under test. The 1320 Bias Current Source can generate up

to 20A of current. A 1320S Slave unit can generate 20A of current. Up to 4 1320S Slave units

may be connected to a 1320 Source for a total of 100A. If a 1320 is connected to the 1730T,

select [LINK 1320] = ON in the MAIN INDEX menu. In MEAS DISPLAY, the BIAS I must be

set ON/OFF and the level of BIAS I must be set.

NOTE:

Before BIAS I can be turned ON and a current level set, [LINK 1320] must be set to ON in the

[System Config] menu under [System Setup].

BIAS I: OFF

When BIAS I is ON, current can be supplied from an external source (1320). To enable/disable

the bias current function, in MEAS DISPLAY (Pg 4/4) press [F1] so that the OFF box is

highlighted. Use the up arrow [⇑] or down arrow [⇓] keys or [F1] to switch the bias current

function ON/OFF. The instrument default setting is OFF.
