BASIC OPERATION - PEAK MODE:
Peak mode is useful for checking balance in pulse ionizing systems. The timer is not
associated with these measurements. The internal high voltage charging source is not
normally used.
The switches used in making peak measurements are the three selector switches under the
PLATE VOLTAGE meter and the ZERO and DECAY switches.
1. Select a meter range using the 5kV/2kV switch.
2. Zero the plate by depressing the ZERO switch.
3. Select desired peak (+ or -).
4. Select PEAK mode by depressing the NORM/PK switch into the PK position.
5. Allow the plate to "float" by depressing the DECAY button. This ungrounds the plate. The
meter will now indicate the highest peak voltage attained by the plate in the selected
polarity. The -
PK/+PK switch may be shifted to the opposite position to read the highest peak voltage
attained in that polarity.
To balance your ionization system or blower, adjust until both positive and negative peak
readings are the same.
6. Anytime the NORM/PK button is released to the NORM position; the peak detector is
automatically reset.
7. The plate will continue to float until the ZERO button is pressed. Thus, the ZERO switch
and the RESET function of the NORM/PK switch are normally used in conjunction with
each other.
