Therefore, 0% = 4mA, 25% =
8mA, 50% = 12mA, 75% = 16mA, & 100%
= 20mA.
6. If adjustments are needed, press zero.
The display now shows:
zero: x.xxx
04.000 +y.yyy mA
x.xxx represents the default zero value
(low scale) and y.yyy is the adjustment
made to 4mA for the analog output signal.
The adjustment can either be positive or
negative shown by + or - respectively. The
top line will alternate between zero: x.xxx
and UP/DN TO ADJUST. This is the zero
adjusted value to calibrate the analog output
to 4mA.
7. Press
↑ or ↓ to increase or decrease the
output until the meter reads 4mA or the
current zero reference matches the field
equipment. Press ent to collect the new
point.
8. Press span. The display shows:
span: x.xxx
20.0 +y.yyy mA
x.xxx represents the default span value
(full scale) and y.yyy is the adjustment
made to 20mA for the analog output
signal. The adjustment can either be
positive or negative shown by + or -
respectively. The top line will alternate
between span: x.xxx and UP/DN TO
ADJUST. This is the span adjusted
value to calibrate the analog output to
20mA.
9. Press
↑ or ↓ to increase or decrease the
output until the meter reads 20mA or the
current span reference matches the field
equipment. Press ent to collect the new
point.
10. Steps 5 - 9 are required only once. They
may be repeated as often as necessary
while in calibration, but only the most
recent point will be saved on completion
of calibration.
11. To permanently store the results of the
calibration press ent, and the unit will
prompt Enter to accept Calibration.
Simply press ent again to save the
calibration. Press esc to abort the
calibration.
