5. Frequency Selection Controls
Three controls select 50, 60 or 400Hz output frequency.
6. Power Factor Control, Lead/Lag Selector, Indicator
A rotary switch selects power factor in steps of 0.1PF over the range 0 to 1. Switch selects either
current leading voltage or current lagging voltage. The indicator is illuminator for PF < 1.
7. Operate/Standby Controls
Two independent momentary push switches, red for Operate and green for Standby. Pushing
the Operate control causes excitation at the output terminals. Pushing the Standby control
removes the excitation. Red (for Operate) and green (for Standby) LED indicators display the
existing state.
8. Keypad
Used to enter voltage, volt-amperes, volt-ampere second or number of events values. The
keypad also incudes keys to enter data, reset the calibrator, and initiate the event count mode of
energy testing.
9. Current Output Terminals
These terminals are used to connect the Series 800 Calibrator to the current coil of the unit under
test. The red terminal is high and the black terminal is low. The current output low terminal is
isolated from the voltage output low terminal. Mating connectors are part number PP100GR and
PP100GB, Superior Electric.
10. Voltage Output Terminals
Output terminals High and Low are connected to the voltage coil or input of the unit under test.
Sense High and Low terminals may be used for a four wire connection, or otherwise are shorted
to their respective output terminals. Mating connectors are part number 23.3000-1 and 23.3000-
4, Interlok.
11. Overload Indicator
This LED is illuminated whenever a current is drawn from the voltage terminals or a voltage is
allowed at the current terminals, which is large enough to cause errors.
12. External Sense
This LED is illuminated when a four wire connection is selected.
13. Voltage Display
Displays the three digit value of the output voltage setting which has been entered through the
keypad. Displays ROM revision level immediately after power up.
14. Volt-Ampere-Second/Events (811A only)
Displays the five digit value of volt-ampere-seconds or the number of events setting which has
been entered through the keypad.
15. Current Display
Displays the value of the current setting, computed from the entries of volt-amperes and voltage.
Displays IEEE-488 address code immediately after power up.
16. Kilovolt-Ampere-Second Multiplier Indicator (811A only)
This LED is illuminated when the value of energy is expressed in kilovolt-ampere-seconds.
