This menu enables you to define Current probes (press A) Current ratios (press V or U, depending on set-up) Press A to define the current probes and ratios. This displays the current probe models detected by the instrument. If a probe is detected but not managed, an error message is displayed. For a 3-wire 3-phase set-up where only two of the three current sensors required are connected, if these two sensors are of the same type and have the same ratio, the instrument simulates the third sensor by assuming the same characteristics as for the two others. The third sensor will be shown in the list as either being simulated, or impossible to simulate. The current probe choices that are available are:
MN93 clamp: 200AAC MN193 clamp: 100 or 5AAC
SR193 clamp: 1000AAC
J93 clamp: 3500A/5000AAC/DC AmpFlex® A193: 100A/6500A/10,000AAC MiniFlex® MA193: 100A/6500AC

SL261 clamp: 100A (sensitivity 10mV/AAC/DC) SL261 clamp: 10A (sensitivity 100mV/AAC/DC) Three phase adapter: 5AAC
If an MN193 clamp (5A range) or an adapter is used, the current ratio setting is proposed automatically. If an MN193 clamp (5A range), an Adapter, an AmpFlex®, a MiniFlex®, J93 or an SL261 clamp is used; adjustment of the ratio, range, or sensitivity is proposed automatically. Use the arrow buttons to define the ratios between the primary current (1A to 60,000A) and the secondary current (1A, 2A or 5A), then confirm the selections with the button.

This graph (Figure 5-65) differs slightly from the previous one because, with the MIN-AVG-MAX mode, there is no loss of information.
The MIN-AVG-MAX mode can be activated for the powers to be displayed (above the graph) the mean power value at the cursor date along with the maximum and minimum power values. Note that, in contrast with the other quantities, only the bar chart of mean values is represented.

The display period of this bar chart is one minute. Since the recording period is one second, each bar of this bar chart represents a value recorded in a one-second window once a minute. The energy calculation mode determines the sum of the powers on the selected bars.

The period of display of this graph is two hours. Since the recording period is one second, each point of this graph represents a value recorded every second taken every two hours. There is therefore a substantial loss of information (7199 out of 7200), but the display is rapid.

Figure 5-69
Item Function 1 Indicates MIN-AVG-MAX mode has been activated.
This graph differs considerably from the one illustrated by Figure 5-68 in that MIN-AVG-MAX mode is activated. Each point of the AVG curve represents the arithmetic mean of 7,200 values recorded every second. Each point of the graph of the MAX represents the maximum of the 7,200 values recorded every second. Each point of the graph of the MIN corresponds to the minimum of the 7,200 values recorded every second. This display is therefore more precise, because there is no loss of information, but it is slower.

5.6 POWER AND ENERGY MODE

The

Power and Energy button displays power and energy measurements. The sub-menus available depend on

which filter is selected:

For 2- and 3-wire single-phase connections and for the 2-wire 2-phase connection, only L1 is available. The filter is therefore not displayed; but the display is the same as for L1.

For the 3-wire 3-phase connection, only the filter selection is available. The filter is therefore not displayed, but the display is the same as for .

On the right side of the screen are a set of filters: 3L, L1, L2, L3, and . Use the and buttons to choose the filter. The values displayed on the Power and Energy screens are dependent on which of these filters is selected; different data will appear for different filters. The following sections describe how these screens appear for the 3L, L1/L2/L3 (all three display the same fields), and filters.
NOTE: This screen corresponds to the choice “non-active quantities separated” in the AR tab of the Calculation Methods menu in Configuration mode. If the choice is “non-active quantities combined” the D label (distortion power) does not appear, and Q1 is replaced by N. This non-active power is unsigned and has no inductive or capacitive effect.
