1.2 Unpacking
Remove the packing list and verify that all equipment has been received.
Upon receipt of shipment, inspect the container and equipment for any
signs of damage. Take particular note of any evidence of rough handling in
transit. Immediately report any damage to the shipping agent.
NOTE: THE CARRIER WILL NOT HONOR ANY CLAIMS UNLESS ALL
SHIPPING MATERIAL IS SAVED FOR THEIR EXAMINATION.
After examining and removing the contents, save packing material and
carton in the event reshipment is necessary. Check to see that the unit is
complete. Included with the calibrator should be a set of test leads, and an
AC adapter/charger.
Become familiar with the designation and polarities of the five jacks located
below the keypad of the calibrator.
2. Operation
2.1 Operating Safety Considerations
• All electrical connections are fused with a 1/8 Amp 2AG size fuse located
on the printed circuit board near the input jacks. These fuses can be
replaced in the field by removing the six(6) faceplate screws and
removing the faceplate to change the fuse in question.
• When using the internal 24 volt power supply to power a device under
test, be aware that the internal power supply is current limited to
approximately 25 mA.
• Do not subject the instrument to pressure beyond its range. This can
easily be controlled by properly setting the air regulator.
• Unless wide temperature changes are experienced, the effect of
temperature may be neglected. Do not use the instrument near a source
of heat or cold. Temperature allowance equals 0.01 percent of full scale
per 1° C change from calibration temperature of 23°C. Temperature
allowance represents the maximum possible error due to temperature.
• Compatible media is clean, dry air. Strong corrosive gases should be
avoided. DO NOT use for liquid service.
2.2 Operating Instructions
NOTE: BEFORE ANY PRESSURE MEASUREMENT CAN BE MADE, THE
CALIBRATOR MUST BE ZEROED OUT. THIS CAN BE DONE BY SETTING
THE SELECTOR VALVE TO THE “VENT” POSITION AND BY PRESSING
THE ZERO KEY. IT IS ADVISABLE TO DO THIS OFTEN TO ENSURE
ACCURATE CALIBRATIONS ARE BEING MADE.
