337 ──────────────────────────────────────────────────── 15.3.1 Replacement Procedure 1 ・This section describes how to replace the 8936 ANALOG UNIT, 8938 FFT ANALOG UNIT, 8939 STRAIN UNIT, 8940 F/V UNIT or 8947 CHARGE UNIT. ・The following procedure describes how to remove the input unit. ・Install the units by reversing the procedure for removal. 1. Remove the input cables from all input units. 2. Power off the 8835-01 main unit, and disconnect the power cord. 3.
338 ──────────────────────────────────────────────────── 15.4 Input Cables 15.4.1 Connection Cable CAUTION ・When disconnecting the BNC connector, be sure to release the lock before pulling off the connector. Forcibly pulling the connector without releasing the lock, or pulling on the cable, can damage the connector. ・Use designated connection cables only. Other cables may interfere with proper connection and measurement accuracy. Use the optional 9197 and 9198 CONNECTION CORDs for the analog input.
339 ──────────────────────────────────────────────────── 15.4.2 9322 DIFFERENTIAL PROBE Connection DANGER When using grabber clips, the 9322’s maximum rated voltage to earth is 1500 V AC/DC; when using alligator clips, it is 1000 V AC/DC. To avoid electrical shock and possible damage to the unit, never apply voltages greater than these limits between the input channel terminals and chassis, or across the inputs of two 9322s. Maximum input voltage is 1000 VAC/2000 VDC.
340 ──────────────────────────────────────────────────── 15.4.3 9018-10/9132-10 CLAMP-ON PROBE DANGER Always connect the clamp-on probe to the secondary side of a breaker. On the secondary side of a breaker, even if the lines are shorted the breaker can trip and prevent an accident. On the primary side, however, the current capacity may be large, and in the event of a short-circuit there may be a serious accident.
341 ──────────────────────────────────────────────────── 15.5 Measurement Errors Caused by Signal Source Internal Resistance ・If the signal source impedance is higher than the input impedance of the unit, a measurement error will occur. ・The input impedance of the 8936 ANALOG UNIT is 1 MΩ. If the signal source impedance is 1 kΩ, an error of about 0.1% will occur.
