4.2.6. DC analogical output
The meter is designed with a DC voltage analogical output depending on the measured
current value and can be used for connection with external data loggers, digital
multimeters, etc.. (see Fig. 2) by using customized cables
CAUTION
Do not apply any vltage to the DCV output of metere durino the recording
operation

1. Select the desired measuring range and consider the herewith conversion values:
AC current range DC output voltage range
300mA 1mV/1mA
3A 1mV/0.01A
30A 1mV/0.1A
300A 1mV/1A
3000A 1mV/10A
Table 1: Conversion values of DCV analogical output
2. Connect the external logger to the DCV output of meter
3. Perform the current measurement (see § 4.3)
