390mV levels are repeated as these are the cross over points from one
channel to the next.
When successfully completed the display returns to the last settings used

D to A Calibration
Equipment required
; - Voltmeter capable of reading 2.0V with a
resolution of 1mV.
The D to A calibration sets the levels of the analogue output. This is
carried out with the on-board voltage reference at zero and +/- 2000mV.
Select the D to A calibration mode by holding the up arrow depressed
while the power is turned on.
The upper display will show ‘dAC mV’ and the lower display will
indicate the mV level that should be available on the Analogue output.
Connect a voltmeter to the analogue output on the rear panel. Select a
range that will display 2000mv to 0.1mV resolution.
The first prompt indicates an output level of -2000mV, use the up and
down and left and right arrow keys to adjust the actual reading on the
voltmeter to –2000mV.
The left and right arrow keys change the output in 5mV steps, the up and
down arrow keys in 0.5mV steps.
When the correct level is reached press the enter key and the prompt
moves on to 0mV, repeat the above for this and the 2000mV levels.
When successfully completed the display returns to the last settings used
in the measurement mode.
