Menu functions The B411 Printer Menu allows you to view and change the printer’s internal settings. Click USER MENU to pull down a list of the menu items. Click the Menu Setting button. Click the B411 icon in the left panel, then click the Device Setup tab.Liaise a wireless LAN connection with MAC Switch-on the Memory 2 Move by pressing the power button at the front panel. Integration of measurement and control functions allow advanced features such as preset on times, auto ranging, and optional printer or computer interface.8.2. Intelligent threshold algorithms provide accurate trip time measurement. This ensures accurate true-RMS readings of current pulses, even with DC offset and distortion, which are typical in primary injection testing.
![]() Mode, the timer starts as soon as current (about 3% of range) is detected after the INITIATE key is pressed, and stops when the STOP key is pressed or a break in continuity is sensed at the CONTACTS binding posts. STOP or RESET will also discontinue current hold.NORMALLY OPEN key: This key is used to set the Normally Open contacts mode when testing a device with an normally open auxiliary contacts. The key may be pressed again to return to normal mode. The LED in the MAINTAIN key will blink while this mode is set, and the vernier motor will be activated whenever the current varies more than 5 amperes from the value displayed when the key was pressed. For test sets with motorized vernier, the MAINTAIN key may be pressed while output is ON to provide automatic current hold feature. When in MAINTAIN mode, the INITIATE key need only be pressed briefly to turn output on. When current stops the timer stops and the final value for pulse current is calculated and displayed as well as the time.PRESET key: This key toggles the PRESET ADJUST mode, indicated by illumination of its LED. In this mode, current is continuously sampled, and when it exceeds approximately 10% of the current range value, the timer starts, and calculation of pulse current begins. This is the normal power-up default mode for the test set, and is recommended for all tests. Keys are pressed simultaneously, both LEDs light, indicating C.L. Timing accuracy in this mode is typically +/- 0.01 seconds.Current Latch key combination: When the N.O. Mode, the timer starts as soon as current (about 3% of range) is detected after the INITIATE key is pressed, and stops when the STOP key is pressed or a break in continuity is sensed at the CONTACTS binding posts. In CONTINUOUS mode, as well as in MEMORY mode before and during a test, the display indicates true-RMS output current in real time. SECONDS or CYCLES timebase may be selected at any time before, during, or after a test.CURRENT DISPLAY: This 4 digit LED display indicates the output current. SECONDS or CYCLES timebase may be selected at any time before, during, or after a test.CYCLES key: This key normally selects the CYCLES timebase. In CYCLES mode, it reads time (based on 60 Hz), up to 999.9 cycles, then autoranges to 9999 cyclesSECONDS key: This key normally selects the SECONDS timebase. In SECONDS mode, it displays time up to 9.999 seconds, then autoranges to 99.99 seconds, 999.9 seconds, and 9999 seconds. When not in PRESET mode, the LED will flash if the displayed time exceeds the preset limit.TIME DISPLAY: This 4 digit LED display indicates the elapsed time of a current pulse. In MEMORY mode (LED on), the current display will read the continuous output current until the test is complete. It may not be accurate for times less than half a cycle.MEMORY key: This key toggles the MEMORY mode, indicated by illumination of its LED. This feature allows the test set to be used to test various solid state trip devices used on circuit breakers. This key may be pressed at any time before, during, or after the test, to toggle between the two modes.
