I. Warning Notice◆ Before using this instrument, please make sure you have read and understand the user manual.
◆ Inspect the calibrator for any damages before use.
◆ Do not apply more than 30V between any two terminals or between any terminal and ground.
◆ When using the calibrator to measure or output the correct wiring, mode and range must be used.
◆ To avoid any potential damage to other devices when testing, please adjust the calibrator to the correct mode before
connecting the test leads.
◆ Replace the batteries as soon as the battery symbol flashes.
◆ Before removing the battery door, remove all test leads from the calibrator.

2. Product Description
ADT209/210 is a multi-function, durable, hand-held loop calibrator. This calibrator offers six primary functions: current
output, analog transmitter output, voltage measurement, switch measurement, transmitter loop measurement, and current
measurement. Each unit comes in a compact, ergonomic design such that the calibrator can be operated easily with one
hand. The large, high contrast VA screen clearly displays the results. Each unit comes standard with an IP54 rating.
The ADT209 provides 0.03%RD accuracy, while the ADT210 provides higher accuracy as 0.01%RD.

Warming:◆To avoid false readings, the battery should be replaced immediately when the display indicates that the battery is low ordoes not start properly◆Use a 9V alkaline battery (ANSI/NEDA 1604A or IEC6LR61)
Battery replacement:
1) Disconnect test lead from the input signal;
2) Long press

key to turn off the calibrator

3) Remove the protective cover;4) Open the battery door behind the calibrator;
5) Remove the battery;6) Insert the replacement battery to make sure thebattery polarity is correct;
7) Replace the battery door and determine that thebatteries are in place;8) Place the calibrator into the leather.
