8.5.2 SETTING THE SECONDARY INPUT SCALE AND DECIMAL POINT
Skip to section 8.5.3 if the secondary input is for an RTD or a thermocouple.
If the Instrument’s secondary input is set as a voltage or current, the Range Values need to be set.
Press the FUNC key until
nonE
and
GROUP
show on the display. Press the ▲ key until
3
shows in
the upper display. Press the FUNC key and the upper display will show the full scale value while
the lower display shows
SI.FSV
. Press the FUNC key until the lower display changes to
SI.LO
. Using
the ▼ or ▲ keys, enter the zero value for the input. For example if the input from a device is 500-
3,000 units, it is 500 units at zero, so enter 500. Press the FUNC key to set the value. The lower
display will change to
SI.HI
. Using the ▼ or ▲ keys, enter the high (full-scale) value for the input.
For example if the input from a device is 500-3,000 units, it is 3,000 units at full scale, so enter
3000. Press the FUNC key to set the value. The lower display will change to
SI.DP
, the decimal
point position for the secondary input. Using the ▼ or ▲ keys, select the position for the decimal
point for this input and press FUNC to lock in the value. Finally, press the RESET key to go back to
the active display.
8.5.3 SETTING THE THERMOCOUPLE TYPE AND UNITS
If the secondary input is from a thermocouple, set the thermocouple type and temperature units, by
pressing the FUNC key until
nonE
and
GROUP
show on the display. Press the ▲ key until
3
shows
in the upper display. Press the FUNC key until the lower display shows
SI.TC
. Press the ▼ or ▲ key
until the upper display changes to the correct value (
tc j
for type “J”,
tc CA
for type “K”,
tc L
for type
“L”, and
tc n
for a type “N” thermocouple). Press the FUNC key to set the value. The upper display
changes to
FAHr
(for Fahrenheit) while the lower display shows
SI.C/F
. Press the ▼ or ▲ key to
change to Celsius
CEL
or if desired.
These inputs are factory pre-calibrated for the following ranges, and require no further calibration.
Thermocouple: Type J -200 - 800°C -328 - 1472°F
Type K (CA) -200 - 1200°C -328 - 2192° F
Type L -200 - 800°C -328 - 1472°F
Type N 0 - 1300°C 32 - 2372°F
RTD Pt100 -200 - 600°C -328 - 1112°F
8.5.4 SETTING THE SECONDARY INPUT FAILSAFE MODE
The Secondary Input Failsafe Mode is a safety mechanism that tells the instrument what to do in the
event of a loss of the Secondary signal. In the event of a Secondary input signal loss, the Secondary
Input Failsafe parameter sets the value of the primary input to full scale (in the default mode).
To set the Primary Input Failsafe Mode, press the FUNC key until
nonE
and
GROUP
show on the
display. Press the ▲ key until
4
shows in the upper display. Press the FUNC key until the lower
display shows
SI.IFS
. Press the ▼ or ▲ key until the upper display shows the correct mode, either
HI
or
Lo
. Press the FUNC key to set the value. Finally, press the RESET key to go back to the active
