Using Calibration Mode
Use Calibration Mode to calculate the NVP value for a known cable length
between 25 ft - 1,000 ft or between 10 m - 300 m. The determined NVP
value can be stored in the unit’s memory allowing you to easily test cables
without recalibrating the NVP every test.
Note:
Calibration Mode is used with unterminated cables only
For the first use of Calibration Mode, the unit defaults to a
cable length of 50 ft, when the unit is set to feet, or 20 m when
the Snap Shot™ is set to meters.
When Calibration Mode is in use, the connected cable is tested
for the presence of voltage. If detected, a dynamic voltage
warning displays until the unit is disconnected from the voltage
source.
1. Connect a cable to the Snap Shot™. Use connection accessories
according to the type of cable you are testing.
Note:
The Snap Shot™ cannot be calibrated without a cable attached
to the unit.
2. Press the POWER button to turn the unit ON.
3.
Press the CAL button. The LCD display screen, illustrated in Figure 5
below, shows the following upon entering Calibration Mode:
▪
The last entered cable length, in units of feet or meters.
▪
The adjustment indicator icon appears in the screen indicating
the cable length is editable.
▪
The “Cal” icon appears in the lower left corner.
▪
Three dashes “- - -” are displayed to demonstrate that the NVP
value has yet to be calculated.
