Using the Timer
The timer portion may be used in two different ways:
First, Voltage Timer indicates time elapsed since the application of the
selected test voltage. The timer begins the count (to a hundredth of
second) when the PUSH-TO-TEST button is pressed. Releasing the
PUSH-TO-TEST button suspends the timer operation. Reapply the test
voltage to start the clock again, beginning at the previously elapsed time.
Second, Discharge Timer indicates the time that elapses during the
portion of the test when the test voltage has been removed.
The timer may also be controlled (start and stop) using the RESET key.
Voltage Timer: This mode causes the timer to begin counting whenever
the test voltage is applied. Begin by toggling to the timer portion of the
display using the CLOCK/TIMER button (this mode is indicated by the
blinking segment(s) on the top portion of the display). Reset to 0 00 00
using the RESET key. The clock will activate each time the PUSH-TO-
TEST button is depressed.
Discharge Timer: This mode causes the timer to begin counting when
the applied test voltage has been removed (i.e., when the PUSH-TO-
TEST button is out). To activate this mode, put the display into the clock
mode (indicated by one stationary segment on top portion of display) and
push/lock the PUSH-TO-TEST button.
With the PUSH-TO-TEST button engaged, switch the display from clock
to timer and push the RESET key. The display will reset indicating 0 00
00.
Note: In the discharge mode (PUSH-TO-TEST button out), the meter
displays the voltage at the terminals. The voltage will drop indicating
discharging of the tested sample.
