PAGE 31
BASIC SETTING Note The P.V status icon lights in red when the voltage measurement circuit detects that the measured value exceeds setting range by 3 folds (CF is set to 3) or 6 folds (CF is set to 6/6A). Auto Range The range is automatically switched according to the voltage and current of input signal. The range is shifted up when either of the following conditions is met. Range is shift up  Vrms or Irms exceeds the measurement range by 130% at CF 3/6.
PAGE 32
GPM-8310 User Manual Example To begin with, the measured Irms value is within the current range of I-Auto 20mA. The measured Irms (27.194mA) exceeds the IAuto 20mA by 130%, so the range is shifted up to 50mA automatically. The measured Irms (3.9994mA) is less than 30% of the I-Auto 20mA, so the range is shifted down to 10mA automatically.

GPM-8310 User Manual The extended event register receives information about changes in the condition register, which indicates the instrument’s internal condition. The information is the result of edge detection performed by the transition filter. The following table lists the bit definitions for the condition register: Bit Name Decimal Definition 0 Updating 1 The measured data is being updated. UPD changing from 1 to 0 indicates that updating has been completed.
PAGE 241
APPENDIX The transition filter parameters detect changes in the specified condition register bits (numeric suffixes 1 to 16) and overwrite the extended event register in the following ways. Condition Definition RISE The specified extended event register bit is set to 1 when the corresponding condition register bit changes from 0 to 1. FALL The specified extended event register bit is set to 1 when the corresponding condition register bit changes from 1 to 0.

APPENDIX Power measurement Method  Direct read method: Directly read the measurement value measured from power measuring instrument.  The average power method: Record the actual power value within a settable period of time and then take the average. A settable period of time isn’t less than 10min. The maximum measurement interval is one second.  Energy accumulation method: Measure the energy within a settable period of time and then divide it by the time to get the power.
