Welcome

The Additel 875 Series Dry Well Calibrators combine excellent performance in stability, radial and axial uniformity, loading with speed, ruggedness and
portability. The Process Calibrator option adds the capabilities of a three-channel thermometer readout and a documenting process calibrator. This
option includes the ability to measure a reference PRT and two devices under test channels, which can measure, mA, voltage, switch, RTD or
thermocouple. When utilizing a reference PRT, the user can control the dry well set point using the external reference PRT for improved performance
and periodic self calibration.

Safety Information

WARNINGS - identify action or condition that may be hazards to the user.
CAUTIONS - identify action or condition that may damage the calibrator or the equipment under test.

WARNINGS：
To prevent personal injury, please follow this user manual.
To prevent possible electrical shock, fire, or personal injury, please:

1. General：

 Check product exterior before use
 Read and follow all instructions carefully
 Dry well calibrator should be used by trained personnel only
 Before initial use, or after storage in humid environments, or anytime the dry well calibrator has not been used for more than 10 days, the dry well calibrator needs to be

started with "Dry-out" function over 2 hours first to meet all safety requirements and specifications, see section 5.3

 Do NOT use the product if it is damaged or operates incorrectly
 Do NOT use in flammable, high humidity, or dusty environments
 Turn off the power switch before unplugging the power cord

2. High Temperature：

 Dry well calibrator has a high temperature warning symbol , this symbol indicates when the block temperature is over 50℃
 Do NOT touch or remove the probe or insert when the high temperature warning symbol is on
 Verify the status of the high temperature indicator prior to each use to avoid potential harm when handling the unit, probes and inserts
 Keep fingers, hands and other body parts clear of the heat shield at all times
 Do NOT touch any part of the dry well other than the touch screen, electrical measurement board and power switch, when the high temperature indicator is Active.

2

3. Electrical：

 Double check power connection, fuse model and installation before use
 Do NOT open the dry well exterior. High voltage is present when the unit is plugged in
 Do NOT apply more than 30V AC or DC to any of the process calibrator inputs (ADT875PC only)
 Do NOT use any test leads other than those provided with the dry well calibrator (ADT875PC only)
 Disconnect all test leads before switching to other electrical measurement functions (ADT875PC only)

CAUTIONS：
To prevent instrument damage, please follow this user manual.
To prevent possible electrical shock, fire, or instrument damage, please:

 Do NOT shake, drop, or bump the calibrator while in use

 Do NOT use any power cord other than the one provided with the dry well calibrator

 Do NOT unplug the power cord while in use

 Do NOT clean the dry well with liquid, please contact Additel for cleaning process

 Do NOT drop anything into the dry well slowly and carful place inserts and probes into the dry well calibrator. To avoid damaging the unit, it is best to use the insert

removal tool when both inserting and removing inserts.

2. Operation

2.1 Main Screen

The main operation interface includes two screens, the upper DUT measurement channel and the lower temperature output channel.
①Status Bar：Includes date and time, cloud storage status , 24V power status , intelligence diagnose center , screenshot , electrical
measurement channel switch , and system menu icon .

Note: All icons (except date and time) on the status bar can be selected via the touch screen to manage and select options.

② DUT measurement window (only for ADT875PC): Includes external measurement readings and sensor type (RTD or TC measurement), automatic
cold junction temperature (only for TC measurement), current or resistance measurements, real-time data of electrical measurement and data analysis
③ Temperature output window: Includes target temperature set point 0.00, real-time temperature data and temperature control play/pause
button .

◆The external PRT sensor can be used as a temperature control sensor: The external sensor window will automatically be displayed when the external
PRT sensor is connected. Please see section 2.3 for how to set the external PRT as control sensor. Once the external PRT has been selected as
control sensor, click on the 0.00 icon in the window to set the target temperature.

④ Screen lock：Press on the top right corner of the screen and select "Screen Lock" to lock the touch display.

◆Unlock：Press on the top right corner of the screen to unlock the touch display.
