6.11. CURRENT MEASUREMENT WITH TRANSDUCER CLAMP (ICLAMP)
The instrument allows the measurement of AC current by using a transducer clamp
(optional accessory HT96U) connected to the ILEAK input (see Fig. 2 - part 26).
1. Press the
FUNC key and select the ICLAMP function. The following screen is
shown on the display
