How to set-up your CalCard
To set up your CalCard correctly requires only a few simple steps:
- Place one probe on either of the two pads on the outside of the card labelled "Common"
- Place the other probe onto each range and jot down the readings
As soon as you get your CalCard you need record the baseline measurements. You should do this as soon as your test equipment has been calibrated to ensure your readings are the most accuracte they can be. Following the two steps above, make a note of each reading.
On the rear of the card is a peel away laminate cover. Carefully peel this back about half way. Then using a fine-tip, felt-pen, write down your readings into each corrisponding box. Return the peeled laminate back down over the results, covering and protecting them. Your CalCard is now ready to use with reliable baseline readings protected on the back.
About The CalCard:
The CalCard verification unit utilises a specific fixed range of resistance values through which the ongoing accuracy and operation of test instruments between calibration periods can be verified:
- Ensure that an instrument's measurement ability does not wander or drift over a determined period
- Functions as a simple check measurement to dispel any doubts an electrician may have about meter readings. This verification is particularly useful when carrying out on-site testing
