1. Push the “1” side of the power switch on the rear panel. 2. Monitor the startup screen for errors as the Product powers up. If an error shows, see Troubleshooting and Error Code. Contact Fluke Calibration for unresolved errors, see Contact Fluke Calibration. -
Page 24: Turn The Product Off
5128A Operators Manual Turn the Product Off Push the power switch on the rear panel to the “0” position to turn off the Product. If the chamber dew point is greater than the ambient temperature, to avoid condensation, do not open the chamber door for 1 hour so that the chamber comes to room temperature. -
Page 25: Condensation Prevention
RHapid-Cal Humidity Generator Operation Condensation Prevention The Product has a condensation-prevention feature that minimizes the possibility of condensation when certain user settings are called for. At high humidities, when the chamber dew point is within 2 °C of the actual chamber temperature, a CAUTION message shows on the lower right hand corner of the display and the controller slows the rate of temperature and humidity change. -
Page 26: Calibrate Uuts
5128A Operators Manual Calibrate UUTs The subsequent sections explain how to do calibrations on humidity probes or UUTs. Recommended Calibration Sequences These recommendations ensure fast, repeatable calibrations of humidity sensors: 1. Do lower-relative humidity calibrations first and ramp up to the higher- humidity levels on each subsequent calibration step. -
Page 27: Insert The Uut
RHapid-Cal Humidity Generator Calibrate UUTs Insert the UUT To make sure the UUT is inserted into the Product chamber correctly, use the working volume template that is included at the end of this manual, see Figure 11. Use one of the probe ports on the chamber door to insert the UUT into the chamber: 1. -
Page 28: Stabilize The Chamber And Uut
5128A Operators Manual For short probes without an available cable, insert the probe into the door as far as possible and do calibrations at or near ambient temperature. This eliminates temperature gradients between the UUT and the chamber. Under these conditions, where the UUT probe is not fully immersed in the working volume, an external reference probe that is inserted at the same depth should be used to ensure the best calibration. -

Page 37: Using A Chilled Mirror Probe
RHapid-Cal Humidity Generator Calibration Using a Chilled Mirror Probe There are different ways to use a chilled mirror with the Product. The subsequent sections outline several of them: • You can draw a gas sample from the chamber as shown in Figure 8. The tube to extract the sample is inserted into one of the ports. - Page 38 5128A Operators Manual • If the chilled mirror has a remote sensing head that fits into one of the door ports, insert the remote head into the door as shown in Figure 9. Ensure that the remote head sensor is inserted into the working volume of the chamber. There is sufficient gas flow within the chamber such that an external pump is normally not needed in this situation.
- Page 39 RHapid-Cal Humidity Generator Calibration • A gas sample from the Sample Out port can be drawn with a chilled mirror that has a pump, returning the gas into the Sample In port. A flow rate of 0.1 liters to 0.5 liters per minute is usually adequate. Ensure the chosen flow rate does not cause excessive chamber temperature non-uniformity.
