- Page 8 Wahl DSTCAL Software User Manual 2) Probe (system) Calibration – Performs the calibration of the RTD probe to the meter electronics. This method can be performed when equipment to measure the probes R0 value is not available. This should not be performed if the R0 value is manually entered into the R0 field.

Page 9: Calibration - Rtd Models
The first system is comprised of the meter electronics. The meter calibration is performed so that the meter will measure resistance accurately. This is accomplished by using known, fixed resistances of a specified accuracy. Wahl recommends using resistances with a known accuracy equal to or greater than 0.009 ohms. The calibration routine also allows entry of the exact resistance. - Page 10 Wahl DSTCAL Software User Manual Averaging Samples Screen 9.

This routine performs calibration of the absolute current. -
Page 16: Dst600 Probe Id
Wahl DSTCAL Software User Manual 7. DST600 PROBE ID 7.1. Theory of Operation Probe ID allows a specific probe to be associated with a specific meter. The meter will only display a temperature when it has the correct probe connected to it. The primary reason for this association is that in case of a failed probe, it helps prevent someone from replacing the probe without going through a calibration process. -

- Page 20 Millivolt Calibration: Used to calibrate the mV measurement capabilities of the meter. This is performed by inserting known millivolt signals via copper wires to the DST400 input connector. If this calibration is going to be performed, it must be performed before the Cold Junction Calibration, as Millivolt Calibration will alter the Cold Junction Calibration.
-
Page 21: Calibration - Thermocouple Models
Meter Calibration is performed to ensure that the meter will measure mV signals accurately. This is accomplished by using known, DC millivolt signals of a specified accuracy. Wahl recommends using mV signal generators with a known accuracy equal to or better than ± 6.0µV and thermocouple emissions of ±0.30°C (includes CJC) at 25°C. -

Wahl DSTCAL Software User Manual A meter calibration was performed successfully on this module. Only Factory calibration set to: (x.xxxxxx mV) 12. Click “OK”. Program displays the following message: 10. TROUBLESHOOTING First check to see which COM Port it is connected to and that the Driver is loaded: 1) Right click the "Windows"... - Page 25 Wahl DSTCAL Software User Manual If the driver is loaded correctly and the correct COM port is enabled, and the unit will still not connect, try the following. Sometimes either the PC com port or the DST com port lock up and this should release it.
