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.
