923 milliK manual - issue: 1.10
The high resistance used makes the input prone to picking up electrical interference, so the
connection to the resistor should ideally use screened cable (see section 4.2). Press the
Numeric
(F2) key, clear the statistics and wait for 100 measurements to be made (when the
display shows “Mean of 100”). The mean value indicated by the milliK should be compared
with the calibrated value of the resistor (apply a correction to the value of the resistor if its
temperature coefficient of resistance is significant). Repeat the procedure on Channel 2.
5.2.3 Thermocouple Voltage Range – Zero Check
Connect a 0mV source (see section 5.1.2 for details of how to make a 0mV short-circuit) to
channel 1 and set the milliK to read voltage by changing the parameters in the ‘Settings’
Window:
Press the
Numeric
(F2) key, clear the statistics and wait for 100 measurements to be made
(when the display shows “Mean of 100”). The mean value indicated by the milliK is the zero
reading for voltage measurement on channel 1. Repeat the procedure on Channel 2.
