The multimeter input terminals are shown in Figure 2-7. The maximum
input on the HI and LO terminals is 300 V dc (450 V ac peak). The
maximum amount of common mode voltage developed between LO and
COM and HI (current) and COM cannot exceed 15 V peak.
A maximum voltage of 300 V dc (450 V ac peak) is allowed on
the multimeter's rear terminals. Multiplexers connected to the
multimeter reduce the voltage that can be applied between the
multiplexer's High (H), Low (L), and Guard terminals, to the
level specified for the multiplexer. For example,
HP E1343A/44A 250 V dc or 354 V ac peak
HP E1345A/47A 120 V dc or 170 V ac peak
HP E1351A
Mixing of multiplexer types reduces all voltage ratings to that of
the lowest rated multiplexer. For example, if an HP E1343A and
E1351A are connected to the same multimeter, then the system
rating is that of the E1351A, which is 14 V.
