It also has a temperature input, requiring the [[P6058]] temperature probe with a 4-pin [[LEMO S-series connector]]. | It also has a temperature input, requiring the [[P6058]] temperature probe with a 4-pin [[LEMO S-series connector]]. The manual states that ''certain NPN transistors such as a 2N2484 may be used as temperature sensors in place of the probe with little or no selection of the transistor''. | ||
The '''DM501 MOD718D''' variant replaced the temperature range with a 200 mV input range providing 10 μV resolution (see [[Media:Physical Measurements Handbook.pdf | Physical Measurements Handbook]]). | The '''DM501 MOD718D''' variant replaced the temperature range with a 200 mV input range providing 10 μV resolution (see [[Media:Physical Measurements Handbook.pdf | Physical Measurements Handbook]]). | ||

==Rear interface== | |||
The DM501 has a rear input, selectable by a front-panel button, on B28 (Hi) / A29 (Lo), and digit-serial BCD outputs (TTL), see below. | |||
The manual does not specify a limit to the input voltage on the rear interface but since this uses card-edge pins adjacent to logic output pins, sticking to the the DM501A specification (200 V peak / 100 V RMS) appears prudent. | |||
