7005 V/I Loop Calibrator v1.3 Operation ON/OFF Control To turn the 7005 ON, press and hold down the ON/OFF/Esc. button until the display powers up. To turn the 7005 OFF, press and hold down the ON/OFF/Esc. button until the display blanks. -
Page 12: Source Mode
Alternatively, when the loop is externally powered, the 7005 provides a sink function. Operation of the 7005 in both source and sink is identical. However, the connections made to the terminals differ (see section 3). Typical source display Actual output (% of span) 75% = 16.00mA... - Page 13 In Measure Mode, ensure the 7005 is in mA units by pressing the V / mA button until mA is displayed on the screen. Note: When the 7005 powers on it will default to Measure mode and the first range mA (4 to 20mA) automatically.
- Page 14 Time Electronics User Manual 7005 V/I Loop Calibrator v1.3 4.4.2 Voltage source The unit can operate as a voltage source up to a maximum of 21V at 20mA. Connection is made via the COM and V+ terminal. Note: These are the same terminals used for voltage measurement and it is therefore recommended that all leads are disconnected when changing from Source to Measure mode.
