2.1 Remove power.
2.2 Connect signal source to the correct input terminals based on the maximum signal
input.
Terminal 7: max. signal input 1 VDC
Terminal 8: max. signal input 10 VDC
Terminal 9: max. signal input 100 VDC
Terminal 10: max. signal input 100 mA
Terminal 12: signal common
2.3 Set Input Range switches (S1 switches 6 through 10) to the desired input range
(See Table 3). Select the lowest possible range that will support the desired
maximum signal. Example: if the desired span is 20 mV to 85 mV, the best range
selection is 0 to 100 mV. The 0 to 200 mV will also suffice, but the accuracy will be
reduced. (0 to 10 VDC range shown).
2.4 Set Input Field/Fact. switch (S1 switch 2) to the off position.
2.5 Apply power to the IAMA and allow a warm up period of five minutes. Follow
the manufacturer’s warm up procedure for the calibration source.
2.6 Set Input Field/Fact. switch (S1 switch 2) to the on position.
The Red and Green LEDs will alternately blink.
2.7 Apply desired minimum scale signal.
2.8 Set Input Field/Fact. switch (S1 switch 2) to the off position.
The Red and Green LEDs will alternately blink.
If the signal is equal or below the minimum limit of the selected range, the Red LED
blinks slowly and the Green LED turns off. Removing power aborts scaling, begin
at Step 2.1.
2.9 Apply maximum scale input.
The Red and Green LEDs will alternately blink.
2.10 Set Input Field/Fact. switch (S1 switch 2) to the on position.
Red LED extinguishes and Green LED becomes solid. Your scaled values are now
saved and recalled if the Input Field/Fact. switch (S1 switch 2) is in the on position
when power is applied.
Red LED will blink slowly if signal is equal to or below minimum limit and blinks
rapidly if signal increases above maximum limit.
2.11 Input scaling complete. Go to Step 3.0 or Step 4.0.
3.1 Remove power.
3.2 For voltage output values, go to Step 3.4
For current output values, continue at Step 3.3
3.3 Set 20mA/1mA switch (S2) to desired full scale output.
(20mA - on; 1mA - off)
3.4 Set Output Field/Fact. switch (S1 switch 1) to the off position.
3.5 Set Output Range switches (S1 switches 3, 4, and 5) to the desired Output Range
(See Table 2). (4 to 20 mA range shown)
3.6 Connect external device to appropriate IAMA output terminals.
Terminal 6: + Voltage
Terminal 5: - Voltage
Terminal 4: + Current
Terminal 1: - Current
3.7 Apply power to the IAMA and allow a warm up period of five minutes. Output
set-up complete.
