2.5.5 CORRECTION
The 1730T instrument provides automatic offset for lead and/or fixture effects. During the offset
process a correction is made (subtracted out) as the result of lead leakage current and stored in
instrument memory to be applied to ongoing measurements. For maximum measurement
accuracy it is recommended that the CORRECTION function be performed on the 1730T
instrument after power up, any time the test parameters are changed and any time the test leads
or fixture is changed.
Prior to performing the CORRECTION function:
• Allow the instrument to warm up for 15 minutes.
• Connect the Test cables (or fixture) to the output connectors (BNC terminals).
• Program the test steps.
With the instrument in STAND-BY status (MEAS DISPLAY shown on display):
• Press [MAIN INDEX]
• Press [F3] = CORRECTION
• Press [F2] = OPEN (or [F3] = SHORT) to select zero function.
• Press [F1] = SINGLE or [F2] = MULTI to select frequency.
• Follow instructions on display: i.e.: “Open circuit test leads”.
• Press [TRIGGER] button.
• Wait while instrument gets CORRECTION value.
• Press [ANY KEY] to return to MEAS DISPLAY status.
NOTE:
When SINGLE is selected, the 1730T instrument performs an open/short at the programmed test frequency.
When MULTI is selected, the 1730T instrument performs the open/short at all 7 test frequencies.
