is visible in the lower alphanumeric portion of the display. The MODE button
changes the mode. This button can be pressed repeatedly until a desired mode
is set. The various modes are listed below in the order they appear. (See Figure
7).
Blank - No data shown
Min/Max - Minimum and maximum measurements (CLR to reset)
Hold - Data stored in the hold registers
Delta(x) - Delta from reference measurement (ENT to set reference)
Units: C/Ω/F/K/R - Set the units of measurement
Rate: 00000 - Set the period for serial transmission
Resol: XXX.XXX - Set the display resolution
CAL MODE - Set probe and instrument calibration parameters (MODE
button must be held for three seconds) See Section 7.8.
Note: Units, Rate, and Resol are temporary modes. The instrument will return
to Delta(x) mode if left in one of these modes when the power is cycled.
