Ultimus I-III Dispenser Pressure Readout, Vacuum Readout, and Dispense Timer Validation
Dispense Timer Validation
The accuracy specification of the Ultimus I–III dispense timer is ±0.05% of the selected time setting. Validation of the Ultimus I–III
dispense timer is performed by comparing an external time pulse that is known to be accurate to the internal timing reference of the
Ultimus I–III. This timing reference establishes the dispense timer accuracy of the Ultimus I–III. The external time pulse is wired to the
“Voltage Initiate” circuit on pins 1 and 2 of the I/O connector and measured by the Ultimus I–III TEACH feature.
The measured TEACH result shown on the Ultimus I–III display will be:
External Pulse Time minus 0.0060 s (seconds).
Ultimus I–III dispensers add 0.0060 s to all dispense times to compensate for solenoid lag.
Tektronix AFG 3021B Function Generator Setup
The Tektronix AFG 3021B function generator, or an other verified pulse generator, can be used. Setup for an AFG 3021B is provided
below. A single external time pulse of 10.0 s is specified to provide a high-resolution measurement.

Validation Procedure
Refer to the Operating Manual for instructions on connecting to the I/O connector and for using the TEACH mode.
1. Configure the pulse generator as described above.
2. Connect the pulse generator output to pins 1 and 2 of the I/O connector.
3. Plug the power supply DC connector into the rear panel power input port.
4. Plug the power supply into an AC power source.
5. Press the power switch to power ON the Ultimus dispenser.
6. Select the TEACH mode.
7. The time display should be zero. If not, press the CLEAR button.
8. Initiate the external 10 s time pulse:
• The Ultimus I–III time display will ideally read 9.9940 s at the conclusion of the
10.0 s initiate pulse.
• For a 10 s initiate pulse, the acceptable readout range is
9.9890 to 9.9990 s [(10.0–0.006) ±0.005 s].
