Or email: register@palmerwahl.com 1. Applications, Key Features, and Models The Wahl DST6xx series is designed for temperature monitoring applications, specifically in the food, dairy and pharmaceutical markets, however it is well suited for any application requiring a high degree of accuracy and reliability. - Page 3 DST600 Series USER MANUAL Self-checking Electronic Circuitry: Meter repetitively checks the electronics • accuracy by measurement of on-board ultra-stable, low ppm precision resistors against embedded firmware values and displays “err” in the event the electronics is out by more than ±0.5°F (0.3°C). The self-checking electronic circuit may be tested by rapidly changing the temperature of the sensor, such as placing from room temperature into ice bath or heated process.

3. Installation Caution! See important information regarding Lithium Metal Batteries in Wahl document #WD1053, before proceeding! Your unit was shipped partially assembled. Installation of the battery by the end- user is necessary as transportation regulations prohibit shipping units with the battery installed. - Page 5 H-frame to seal the panel opening. 3.3.2. For detailed installation instructions see Wahl document WD1100 and reference Wahl drawing 13615, both included in section 11 of this manual. 3.4. Wire Connections – In the event that your probe was shipped disconnected from the meter, the following describes the probe wiring and installation process.

For other DST6xx series, 2 clamp-on ferrites are included to minimize RFI susceptibility. These ferrites should be placed around the internal wiring.

Positive terminal should be at the top of the PCB. 4.1.4. - Page 9 DST600 Series USER MANUAL 5.4. Error Codes - During normal operation, the DST6xx continually performs diagnostic testing on the sensor lines. Errors are indicated by the following error codes: Error Code Description Reading is above meters usable range Reading is below meters usable range or sensor is shorted CbL1 Indicates cable 1 is open (J1 pin 1) CbL2...

Quality Control System requires either “no positive error” or a lesser amount of positive error, for example, +0.2°F maximum error. It is possible on the Wahl DST6xx series thermometer to offset the error to achieve this accuracy. It should be noted that in doing this, there may be a slightly larger negative error at some temperatures;... - Page 11 DST600 Series USER MANUAL To achieve this we will be using the programmable RO value in the DST6xx Series TID, which is accessed using the DSTCAL program. The R0 value (R0 stands for resistance at 0°C), is a variable in the equation for converting resistance to temperature for platinum RTD’s and is factory set to match the specific value of the probe connected to the DST6xx.

DST600 Series USER MANUAL 8. DST610/650, DST611/651, DST620/660, and DST621/661 Models DST610/650, DST611/651, DST620/660 and DST621/661 are variations of the DST600/640 that include an isolated secondary sensor housed in the same probe shank. This enables the user to have an independent signal from the same probe for use by a controller or recorder. - Page 14 This option requires the use of a connecting cable or connector (ordered separately).

- Page 15 DST600 Series USER MANUAL 8.3. DST620/660 – Consists of DST600/640 meter with an isolated secondary sensor and 4-20 mA programmable transmitter. Transmitters are programmed at the factory. The DST620/660 provides an isolated current output from the same probe shank. This reduces the number of penetrations made into the process and reduces error due to non- uniformity of the process.
