Thisapplies independently of the selected setting for "indicate wire break/short circuit"(see section "Register assignment", Register 32).5.2.1.2.3 Influencing a Measuring Circuit Channel through a Quick Change inTemperatureAs a rule, temperatures change relatively slowly. If a channel's applied resistancechanges over a short period of time by a large resistance value (large in relation tothe converted temperature change), then this can influence the other channelwithin the measuring circuit.5.2.2 750-464 (RTD) Version, 2-Channel Operation5.2.2.1 2 x 2-WireFigure 14: Connection example, version 750-464 (RTD), 2-channel, 2 x 2-wire
