*1 Conforms to JIS B 3502, IEC61131-2
Number of sweeps: 10 times respectively in the X, Y, and Z directions (80 minutes)
*2 Select with the setting switch.
*3 Even if a voltage that exceeds the input range has been input, if it is within the displayable range, it will be displayed (up to 10,999 can be displayed with an absolute value). In this case, display will be performed from the lowest digit; the upper 2 digits will be displayed with A flashing. (Ex: When using 10.500 V input with a range of 2 (input range ±10 V), A.500 is displayed) If a voltage that exceeds the displayable range has been input, FFFF (-FFFF) will be displayed. Also, when scaling is in effect, if the measurement value exceeds the displayable range with an input voltage in the input range, EFFF (-EFFF) will be displayed.
*4 When scaling is enabled, the maximum resolution is 0.5 mV (1/20000).
*5 In the direction of transmission/reception when seen from the master unit.
*6 The <> do not support a communication speed of 5 Mbps.
