Special safety requirements
1. WARNING – DO NOT OPEN WHEN AN EXPLOSIVE ATMOSPHERE IS PRESENT
2. WARNING – DO NOT CHARGE THE BATTERY IN HAZARDOUS LOCATION
3. WARNING – USE ONLY the approved batteries
4. The equipment needs to protected from impacts with high impact energy
5. Do not touch the non-metallic enclosure or touch with the insulating materials only
6. The batteries used in the equipment with same manufacturer, same models and same electrochemical system
7. The conformal coating is applied to PCB boards was declared meet the requirements of IEC 60664-1 and IEC
60664-3 by manufacturer
8. Tamb: -20°C to +50°C.
9. USB port only to be used in Non-hazardous area.
10. PX connect with pressure measuring module CDPX-Ex only; the connected cables and flexible hose used for the
external pressure modules are made of insulation materials, so end user should consider the risk of electrostatic
discharge during material selection and installation process
11. Metallic parts (only fasteners) presented a maximum capacitance of total 110pF, end user should consider this risk
for suitable application
12. No additional input energy limitation are required for Type-C USB port and DC charging port when Um does not
exceed 250V (internal OVP/OCP are designed in line with IEC 60079-11)
13. Do not remove the silicone rubber protective sleeve from the enclosure of equipment in Hazardous area
14. IS parameters must be strictly observed in full for different external measuring ports on the different models in
accordance with Ex instruction

1. Introduction
1.1 Product Overview
Additel's 273Ex is an intrinsically safe handheld multifunctional pressure calibrator with a color touchscreen,
smartphone like interface, built-in quick test tasks and optional HART communications capability. This innovative Additel
product drastically improves explosion-proof field testing and calibration. The Additel 273Ex has a built-in atmospheric
pressure sensor, so that absolute pressure and the gauge pressure are easily facilitated. With three pressure module
inputs, one switchable at the bottom and two digital inputs on the side, the user can configure the setup accordingly and
easily meet the needs of pressure calibration and testing in virtually any environment.
