WARNING:The battery may ully discharge when recording or long periods o
time while not connected to a power supply. The PowerPad will continue to
record or some time, even i below the minimum battery charge value. However,
the display may not come back on, and will eventually stop saving data when the
battery is too low. All data recorded will be saved.
I in the Record Mode, and the display does not come ON, do not turn the instru-
ment OFF. Supply power to the PowerPad with the line cord and the display will
come back ON when any button (other than ON/OFF) is pressed.

3.11 Three-phase5AAdapterBox
This adapter is a three-phase adapter with three 5AAC inputs L1, L2, L3 and three
AC voltage outputs. All circuits are independent and isolated between input and
output. The outputs are equipped with connectors to mate with the PowerPad
Model 3945 current channel inputs. It facilitates automatic sensor recognition and
probe ratio programming for both 1 Amp and 5 Amp output probes. Additionally, the
adaptor box can be used directly in series in a 5 Amp circuit.
WARNING: This adapter is rated EN 61010, 300V, Category III and permits the
use of standard current probes with either a 1 Amp or 5 Amp output.
The input connections accept either 4mm male plugs or rigid leads between 1and 2.5mm2 inserted in the side hole after pressing the spring loaded connector
down to expose the hole.
3.11.1 ConnectingtoSecondaryCurrentTransformer(CT)
WARNING: Use caution when connecting to a secondary current transformer
1. Short the two leads of each secondary current measurement transformer.
2. Never open a secondary circuit of a CT if its primary circuit is connected to a
supply voltage. In any case, disconnect the primary measurement transformer
circuit from the supply network.
3. Connect each CT secondary to the input of the 5A adapter in the correct order
(ground on P2) and the right phase order L1, L2, L3.

NOTE: Neutral current is calculated, not measured, in the 4 wire hookup.
V1 must be connected in all hookups, since the display is synchronized rom V1and the network requency measured by V1.
Neutral current is calculated by adding, for each datapoint, each of the 3measured phases of current. This assumes that all current ows through
neutral. This results in a 256 datapoint waveform. If the 3 phases of currentwere balanced, the calculated neutral current would be 0 for every datapoint.
