Can Dataforth provide calibration reports for modules I purchased?
Yes we can provide calibration reports for the modules that you purchased.
You can either
a) visit https://www.dataforth.com/TestDataReport.aspx to search for Test Report Datasheets by Serial Number or
b) you can send us a list of model numbers and their serial numbers to email@example.com
Is an external conversion resistor required in order to use the DSCT32 module?
No, an external conversion resistor is not required in order to use the DSCT32 module. The current/voltage conversion is achieved by an internal resistor as shown in the block diagram in the data sheet.
An external conversion resistor in the case of the DSCT32 could be used to shunt off some of the current from the module and allow a larger input current range; then they could also be used with voltage input modules to convert a non-standard current range into an input voltage range.

On DSCA’s, what are the zero and span adjusters physically?
The DSCA and DSCT zero and span adjustments are made using trimpots located under the front panel label and are non-interactive for ease of use. The trimpot screw heads are behind perforated circular knockouts labeled Ø and <->. The screw heads are slotted to accept a narrow flat blade screwdriver. The zero and span adjusters are 25Turn trimpots.

Does Dataforth have any options for thermistor input?
Thermistor interface has never been designed for SCM7B, 8B, DSCT, or MAQ20 product lines. However, we do have some custom products in the SCM5B line that can accept thermistor interface. Any SCM5B36, SCM7B36, 8B36, DSCA36, DSCT36 module with potentiometer input 0-10kohm may also be suitable for some sensors.
How do I mount and remove a DIN rail module?
To mount the module, do the following.
With the DIN rail mounted horizontally on a vertical panel, hang the hook at the top rear of the module over the top edge of the DIN rail.
Then rotate the module down so the bottom rear corner of the module touches the bottom edge of the DIN rail.
Then push on the bottom front corner of the module until you hear and feel a click. Push and pull the front of the module to ensure it is securely held on the DIN rail.
To remove the module, do the following.
Using a small screwdriver, insert it into the slot on the movable clip (red for DSCA & DSCT) under the bottom rear corner of the module.
Rotate the body of the screwdriver toward the body of the module until the movable clip disengages the bottom edge of the DIN rail and you can rotate the module upward.
Then you can unhook the module from the top edge of the DIN rail.

How does the load resistance of a module affect the noise at the output?
Noise at the output of a module is independent of load resistance.
If a thermocouple is soldered to a lead that has current running through it, how do you avoid affecting the thermocouple signal and subsequent measurement?
The thermocouples must be isolated so current does not come from the circuit under test and run through them. SCM5B, SCM7B, 8B, DSCA, DSCT, MAQ20 all offer the required isolation.
What is the MTBF for DSCT32?
The MTBF for DSCT32 is 624,000 hours.
