7.2.12 Lower input & display ‘in-Lo’
This function, which only appears in the menu when
the transmitter is configured for a voltage or
resistance input, defines the transmitter lower input
voltage or resistance ‘inVAL’ and the corresponding
transmitter digital display ‘diSP’.
This function does not affect the transmitter output
current which is defined by the ‘CAL’ function.
The ‘in-Lo’ function may be selected from within the
configuration menu by operating the
▼ or ▲ button.
To enter the function press
P
which will display
‘inVAL’ in the sub-menu, pressing
P
again will reveal
the existing transmitter lower input voltage or
resistance. ‘InVAL’ is shown in units which depend
upon how the transmitter input ‘inPut’ has been
configured, as shown below:
Configured ‘inVAL’
transmitter input units resolution
Voltage mV 0.1 or 0.01mV
Resistance Ω 0.1 Ω
‘inVAL’ may be adjusted using the ▼ or ▲ button to
adjust the flashing digit and the
P
button to move
control to the next digit. When configured for a
voltage input, operating the
P
button when the 0.1mV
digit is flashing increases the resolution to 0.01mV
which is indicated by the display colon being
activated. When the required input has been
selected, press
E
to enter the selection and return to
the ‘inVAL’ prompt in the sub-menu.
‘diSP’ which is the transmitter display corresponding
to ‘inVAL’ may be selected from within the sub-menu
by operating either the
▼ or ▲ button. To enter the
function press
P
which will reveal the existing lower
transmitter display. The display may be changed
using the
▼ and ▲ buttons to adjust the flashing digit
and the
P
button to move control to the next digit.
The position of the displayed decimal point is set by
the dP function – see section 7.2.11. When the
required transmitter display has been selected, press
E
twice to enter the selection and return to the
configuration menu.
Note:
When the displayed decimal point has been
set to autorange, it may be necessary to manually
position the decimal point before adjusting ‘inVAL’.
This can be achieved by repeatedly operating the
P
button until the activated decimal point flashes, the
decimal point can then be positioned using either the
▼ or ▲ button. Pressing the
P
button again will
return control to one of the digits.
7.2.13 Higher input & display ‘in-Hi’
This function which only appears in the menu when
the transmitter is configured for a voltage or
resistance input, defines the transmitter higher input
voltage or resistance ‘inVAL’ and the corresponding
transmitter digital display ‘diSP’.
This function does not affect the transmitter output
current which is defined by the ‘CAL’ function.
The ‘in-Hi’ function may be selected from within the
configuration menu by operating the
▼ or ▲ button.
To enter the function press
P
which will display
‘inVAL’ in the sub-menu, pressing
P
again will reveal
the existing transmitter higher input voltage or
resistance. ‘InVAL’ is shown in units which depend
upon how the transmitter input ‘inPut’ has been
configured, as shown below:
Configured ‘inVAL’
transmitter input units resolution
Voltage mV 0.1 or 0.01mV
Resistance Ω 0.1 Ω
‘inVAL’ may be adjusted using the ▼ or ▲ button to
adjust the flashing digit and the
P
button to move
control to the next digit. When configured for a
voltage input, operating the
P
button when the 0.1mV
digit is flashing increases the resolution to 0.01V
which is indicated by the display colon being
activated. When the required input has been
selected, press
E
to enter the selection and return to
the ‘inVAL’ prompt in the sub-menu.
‘diSP’ which is the transmitter display corresponding
to ‘inVAL’ may be selected from within the sub-menu
by operating either the
▼ or ▲ button. To enter the
function press
P
which will reveal the existing higher
transmitter display. The display may be changed
using the
▼ or ▲ button to adjust the flashing digit
and the
P
button to move control to the next digit.
The position of the displayed decimal point is set by
the dP function – see section 7.2.11. When the
required transmitter display has been selected, press
E
twice to enter the selection and return to the
configuration menu.
Note:
