Seagate FR-A7AY instruction manual Instructions

EXTENSION ANALOG OUTPUT

4.6 Instructions

(1)A voltmeter having smaller internal impedance (or an ammeter having larger internal impedance) than the value indicated in the Specifications may not deflect to full-scale and may not be calibrated.

(2)When calibrating a meter which has a small full-scale value, set the output of terminal AM0 (or AM1) to the minimum without the meter connected. Then, connect the meter and make calibration.

CAUTION

This option unit is factory-set to provide the full-scale output of 10VDC and 20mADC. Hence, a voltmeter (7VDC or less) or an ammeter (14mADC or less) with a small full-scale value may be damaged accidentally during calibration. This should be fully noted.

(3)Set "0%" in Pr. 307 (Pr. 311) and "100%" in Pr. 308 (Pr. 312) when calibrating Pr. 323, Pr. 324, C0 (Pr. 900), C1 (Pr. 901) when Pr. 309 = "10 or 11 " to prevent calibration value deviation.

(4)When an option error occurs, all outputs are tuned off.
