DM44 optional
From the 1978 Tek catalog:
475 $3195
475A $3555
475 DM44 $3640
475A DM44 was available as
option -44 add $445
option -45 add $360 (w/o temperature probe)
We had both varieties where I worked. As Demian said it wasn't as good as the better handheld meters. But we always had our scopes on scopemobile carts so this way we never had to go find a meter or a place to put one. One feature that it had was very useful. The DM44 would also display time offset between channels which made it very useful to check for adequate setup time in asynchronous interfaces. CH1 on input, CH2 on output, turn the knob to slide one trace until the edges lined up and the numeric display would tell you the time differential.

question on TEK differential probe
Are you familiar with differential probe TEK P6046? I'm considering one to test laptop circuits and low power audio amps.
- Will a probe like this accept only proprietary extensions?
- Is it more cost effective to invest in something more modern - input max voltage on this is 25 Volts.
Thanks
