The 06 is an upper-board option which adds a single setpoint for digital control or alarm to a host digital panel meter. Its outputs are one Form-C reed relay, one TTL output and one front-panel LED, which flashes when the meter reading is in the alarm zone.

OPERATING MODES
The 06 can be hardwired for latched or non-latched operation. In latched operation, the alarm outputs stay activated until reset by a front-panel reset pushbutton or momentarily grounding a pin on the rear connector. In non-latched (or automatic-reset) operation, the alarm outputs are only activated while the input to the meter is in the alarm zone. If the polarity pin is not connected, the 06 will alarm on the absolute value of a positive or negative signal. This allows operation as a null-band detector.

PROGRAMMING
The 06 is programmed by hardwiring selected BCD lines from the main board of the meter. When all of the selected BCD lines go true, the 06 senses an alarm condition.
