VOM Use

Codes are shown as voltage pulses (needle sweeps). Pay careful attention to the length of the pauses between sweeps in order to read the codes correctly. There will be a 1/2 second pause between the number of sweeps indicating a digit and a 2 second pause between each digit in a code.

For example, code 23 is reported by three needle sweeps with a 1/2 second pause in between each, a two-second pause to indicate the start of the second digit, then three sweeps with the 1/2 second pause between the sweeps. There is a four-second pause between codes when more than one code exists. See Figure.

There will be a 4 second pause between each code when more than one exists. During the KOEO Self-Test, On-Demand codes are separated from Continuous Memory codes by a 6 second delay, a single 1/2 second sweep (Separator), and another 6 second delay.
