This terminal is fuse protected. For your safety during continuous measurements, keep the duty cycle as 30 seconds in use and 15 minutes in rest. 200mA MAX FUSED The maximum current that you can measure at this terminal is 200 mA DC/AC. This terminal is limited to 2 amps by a fuse. 500V MAX To avoid electrical shock or instrument damage, do not connect the common input terminal (COM) to any source of more than 500 V with respect to earth/ground. MAX 750V AC 1000V DC The maximum voltage this meter can measure is 1000V DC or 750V AC. Be extra careful when making high-voltage measurements. DO NOT TOUCH THE TERMINALS OR PROBE ENDS. SAMPLING RATE.....................................................Variable Note: Sampling rate is defined by software. Refer to the complete operating instructions. Specifications are typical; individual units might vary. Specifications are subject to change without notice. (br/ir-07/06/95)
