WA2000
SOLDERING IRON ANALYZER
INSTRUCTION MANUAL
INTRODUCTION
The WA2000 soldering iron analyzer was developed for testing soldering irons for compliance with the DOD-STD-2000 and the new MIL-STD-2000 specifications. This portable unit is capable of testing tip temperature, tip to ground resistance and tip to ground noise (mVRMS). Correctly used and maintained, it is the most accurate of any comparable tester currently available on the market. Please read this document thoroughly, prior to using the WA2000.

TIP TEMPERATURE MEASUREMENT
The unit has the ability to check for either temperature stability ( T) or absolute temperature. To perform these tests, two methods must be used.
TEMPERATURE STABILITY
This test is used for compliance with the MIL-STD-2000 requirement. The detachable contact pyrometers were designed for use in this test. The pyrometers will not give accurate absolute measurements. Due to loading effects, the temperature measured will be lower than the actual tip temperature (about 30°F or 17°C); however, stability can easily be checked with the pyrometer. The T measured has an accuracy of better than
±0.1% over a ten degree span. This is more than adequate to fulfill the temperature measurement requirements of the MIL-STD-2000 specification.
ABSOLUTE MEASUREMENT
The K-111 and K-181 thermocouple assemblies have been provided for making absolute temperature measurements. These assemblies can also be used to monitor active soldering and can measure temperature loading, excursions and heater response. Although not a requirement for compliance to the MIL-STD-2000 specification, it does provide a good tool for process control and improvement.
MEASUREMENT PROCEDURE
1.Set the rotary selector switch to the TEMP position and the slide switch to °C or °F to select the desired unit of measure.
2.Plug either a contact pyrometer or thermocouple assembly into the TEST receptacle. If using a pyrometer, place the tinned tip of the iron to be tested onto the contact pyrometer. Using the iron "holder" provided with the WA2000 will aid in obtaining an accurate reading. Add additional solder to increase contact area to each side of the pyrometer. Response time will be 5 seconds or less.
3.Record both the low and the high temperature reading and calculate T = (TH - TL).
***PLEASE NOTE ***
The ground adapter is provided for testing tip noise and resistance only. For temperature measurements, the ground adapter must not be connected to the tester or temperature errors can occur.
