Also see "Calibrating the meter". Closing a jumper will bypass the resistor in the resistor ladder. Option Description J3 to J10 Closed Leaving a jumper open will enable the resistor in the resistor ladder. Open Connecting to VSS will allow only negative energy to be measured. J11 VSS Connecting to VDD will allow only positive energy to be measured. VDD Connecting to jumper DIRO / DIRI will allow bi-directional energy measurement. (Bi-directional is where both positive and negative energy is measured) DIRO / DIRI Used to select the required rated conditions. See table 3 and 4 as well as figure 5 for further details on the various settings available. J14 VDD (+) VSS Used to select the required rated conditions. See table 3 and 4 as well as figure 5 for further details on the various settings available. J15 VDD (+) VSS Used to select the required rated conditions. See table 3 and 4 as well as figure 5 for further details on the various settings available. J16 VDD (+) VSS J18 VSS Used to select between fast and normal pulse output mode on the calibration LED output. When connected to VSS the normal pulse output mode is selected. J17 VSS Connecting to VDD selects the fast output pulse mode. VDD (+) When fast mode is selected this input can be used to enable or disable the internal pulse stability circuitry for the LED output pulses. Connecting to VSS disables this circuitry. J19 VSS (-) Connecting to VDD enables this circuitry. This selects the IC manufacturer’s test mode. For normal metering connect to VSS. VDD (+) |
