NOTE If a signal was applied to the Channel 2 input connector prior to turning
on the Counter, CH2 NO SIGNAL is displayed momentarily. As soon as the
Counter acquires the input signal, it displays the signal’s value.
NOTE The internal Reference Oscillator requires 10 to 15 minutes to reach a
stable operating temperature. Since the Reference Oscillator receives
power only when the Counter is on or in Standby mode, no measurements
should be taken unless the Counter’s Main ~ Power switch has been in the
on (1) position for at least that amount of time.
Turning the Display Backlight Off or On
When you first turn the Counter on, the backlight for the LCD display is
always lit. You can toggle the backlight off and on by pressing the Shift
key and then the On/Off (Clear) key, as shown below.
NOTE If your Counter has the Battery option, you can extend the length of time the
Counter can operate from the batteries by turning off the display backlight.
