Reactive Power, Active Energy): ( 1. ) Active Power(kW) and Power Factor (PF) (Figure 8 ) a. Press kW / PF button, the Active Power value is shown in the primary display and the Power Factor value, “PF” symbol are shown in the secondary display. When the Power Factor value is negative, the loading is capacitive. - 15 - b. The maximum measurement range of Active Power is 600kW. For exceeding the maximum value, the “OL” symbol will be shown in the display. If test voltage exceeds 600V or the test current exceeds 1000A, ...

- 28 - When the LCD displays the “ ” symbol, the batteries must be replaced to maintain proper operation. Use the following procedure to replace the batteries: 1. Disconnect test leads from any signals, turn the rotary function switch to OFF, and remove the test leads from the input terminals. 2． Open the battery cover and remove the battery cover. Because there is a locked design in the battery cover. Don’t force the battery cover open, otherwise the cover is broken. Refer to Figure 23 for opening it: Insert a coin into the groove of th ...
