Current Output (rng) sub-function

This sub-function lets you set the transmitter current output range of this unit. The difference between
the upper and lower range has to be a minimum of 20% of Full Scale, anywhere on the scale.
7.6.1

Entering current output sub-function

1) Enter Advanced Set-up mode. Push the ENTER key and scroll
to Advanced Set-up security code "22". Push the ENTER key
again.
2) Press the ▲ or ▼ keys to scroll until the upper display shows
"rng". Press ENTER.
3) Measurement range selection. Please refer to 7.5. Press
ENTER to proceed to current output sub-function (7.6.2)
7.6.2

Choosing the output type

This parameter lets you choose between 0-20 mA or 4-20 mA output.
1) Follow directions in 7.6.1 to enter Current Output mode.
2) Press the ENTER key. Scroll with the ▲ or ▼ keys until the
upper display shows the output type (0-20 or 4-20), and the lower
display shows "out".
3) Press the ▲ or ▼ keys to select your output type: 0-20 or 4-20
mA.
4) Press the ENTER key to confirm your selection.
5) Proceed to 7.6.3, or return to Measurement mode by pressing
the ▲ and ▼ keys simultaneously (escape).
7.6.3

Selecting Conductivity value at 0(4)mA

This parameter lets you choose the conductivity value at which the
transmitter output will be 0(4) mA.
1) Follow directions in 7.6.1 to enter Current Output mode.
2) Press the ENTER key. Scroll with the ▲ or ▼ keys until the
upper display shows a conductivity value and the lower display
shows "r.0(4)".
3) Press the ▲ or ▼ keys to select the required conductivity
value to be equivalent to 0(4) mA (0.00 to 80.0 % F.S.; Default is 0% F.S.).
4) Press the ENTER key to confirm your selection.
5) Press the ENTER key to return to Advanced Set-up mode, or return to Measurement mode by
pressing the ▲ and ▼ keys simultaneously (escape).
