Changing the Threshold
1)
Turn off the Ground Set Tester.
2)
Place the ‘CONTINUOUS TEST’ switch in the ‘OFF’ position.
3)
Hold down the ‘CABLE SIZE’ and the ‘SINGLE TEST’ switches simultaneously. Power
up the unit. The display should read ‘THRESHOLD CHANGE MODE’. Release the two
switches. After three seconds, the display switches to ‘VOLTAGE ACROSS MAN AL-
LOWED 60V’.
4)
Refer to Figure 2. The voltage displayed on the second line will be the voltage across the
man used to calculate the maximum values for the thresholds. This voltage can be adjusted
using the ‘CABLE SIZE’ and the ‘CONTINUOUS TEST’ switches as described in 5 & 7.
5)
Select and underline the number to be changed by using the ‘CONTINUOUS TEST’ switch.
6)
Use the ‘CABLE SIZE’ switch to change the number of the voltage that is underlined. The
number will increase to 9 and then change back to 0. The number on the left will change
between 0 and 2.
7)
When the desired voltage is displayed, press the ‘SINGLE TEST’ switch. If you enter an
incorrect voltage, start again from Step 1.
