How to use REED VC-05 Loop Calibrator
Current output with Reed VC-05 For current output function connect one end of the test leads to the +mA -output jack of the calibrator (I/O terminals) and connect the other end with the input of the user’s instrument. Switch the calibrator into the output mode by pressing the key “OUTPUT/IN/SW” and select the mA or % scale. Now your instrument are ready for current output. Using the current output function, with Reed VC05 another features such 25% Step Current Output, Auto-ramp, Simulating Transmitter Output(XMT) or Current Output Set For Zero Point & Full Scale are also easy to use and set. During the operation of the current output, try your best to use the external 24VDC power supply in a mode of connecting a transmitter, thus being able to prolong the working life of the battery.
Calibrator Measurement For To measure the DC Current with Reed Loop Calibrator VC05 starts with connect the output of the user’s instrument to the calibrator, using the test leads. Using the “OUTPUT/IN?SW button, switch the instrument into INPUT mode and select the input to be set in mA or %. The calibrator starts measurements, and then the symbol ‘ON’ appears in the display followed by the result of measurements.
Measuring DC Voltage will be available after inserting the test leads into the V input jack of the calibrator and select the V function.
Providing 24V Power Supply For Measuring Loop Current Insert the test lead into the +LOOP & mA input jacks of the calibrator. When the key [OUTPUT/ IN/SW] is pressed, the symbol ‘INPUT’ appears in the display. It denotes that the calibrator is in an input state. After choosing the scale ,mA or mA% (0% denotes 4mA and the value of 100% denotes 20mA), the calibrator starts measurements, and then the symbol ‘ON’ appears in the display.
Measuring Switching contact Status Insert one end of the test lead into the switching contact measuring jack of the calibrator and connect the other end to the switching contact of the user’s instrument. When the key〔OUTPUT / IN/ SW〕is pressed, the display indicates the symbol ‘INPUT’ followed by the word ‘CLOSE’ or ‘OPEN’ according to the measured switching contact status. When the switching resistance exceeds 15KΩ, the contact is regarded as an off state.
