Precautions - Mitsubishi Electric 800 Series Instruction Manual

Precautions

• When using a voltmeter with a lower internal impedance or an ammeter having a greater internal impedance than the value
indicated in the specifications (Refer to
cases.
• When calibrating a meter with small full scale, first adjust the outputs from the terminals AM0 and AM1 accordingly, then
connect the meter.
CAUTION
• This product is initially set to provide the full-scale output of 10 VDC and 20 mADC. Voltmeters (7 VDC or less) or ammeters (14 mADC or
less) with a small full-scale value may accidentally be damaged during calibration. Use caution.
• When calibrating the meter using Pr.323, Pr.324, C0 (Pr.900), and C1 (Pr.901) while Pr.309 = "10 or 11", set "0%" in Pr.307
or Pr.311, and "100%" in Pr.308 or Pr.312 to prevent calibration value deviation.
• All the outputs are shut off when a protective function (E.1) is activated.
