LEXAN®polycarbonate (PC) film, Buttons: silicone rubber
Noise Filter: Averages the input signal over a period of time between 1
and 16 seconds to dampen the effects of a noisy signal that causes a
jumpy display.
Filter Bypass: 0.0 to 99.9% of full scale. Input signal changes greater
than bypass value are displayed immediately.
Recalibration: Recalibration is recommended at least every 12 months.
Max/Min Display: Max/min readings reached by the process are stored
until reset by the user or until power to the meter is turned off.
Tare: Zeros out display
Password: Programmable password restricts modification of programmed
settings.
Non-Volatile Memory: All programmed settings are stored in non-volatile
memory for a minimum of ten years if power is lost.
Normal Mode Rejection: 64 dB at 50/60 Hz
Connections: Removable screw terminals accept 12 to 22 AWG wire.
DI Digital Input Contacts: 2.1 VDC on contact. Connect normally open
contacts across DI+ and DI-
DI Digital Input Logic Levels: Logic High: 2.4 to 30 VDC (max)
Logic Low: 0 to 0.9 VDC
Tightening Torque: Screw terminal connectors: 4.5 lb-in (0.5 Nm)
Mounting screws: 8.0 lb-in max. (0.9 Nm)
Overall Dimensions: 4.68" x 2.45" x 3.79"
(119 mm x 62 mm x 96 mm) (W x H x D)
Weight: 8.7 oz (247g) with option board
Warranty: 3 years parts and labor
Common Open Collector & Relay (Alarm)
Specications
High or Low Alarm: User programmable for high or low alarm
Alarm Deadband: 0-100% FS, user programmable
On & Off Time Delay: 0 to 9,999 seconds
Fail-Safe Operation: Independent for each open collector and relay
Fail-safe: on, the output is on under normal conditions
Fail-safe: off, the output is on under alarm conditions
Alarm Operation: Automatic, Automatic with manual override, Latching
(manual reset anytime), Latching with reset after cleared (manual reset
only after alarm has cleared)
Alarm Indication: Red backlight, flashing display, alarm symbol (!)
(symbols not available on bargraph models) Bargraph segment flashes on
alarm.
Alarm Message: On or Off; User programmable, 8 characters maximum.
Displayed every 10 seconds for 1 second on bottom line
Alarm Acknowledge: Front panel ACK button or external digital input
resets output and screen indication
Auto Initialization: When power is applied to the meter, open collectors
and relays will reflect the state of the input to the meter
Timer Output: One-shot or Continuous
Off Time Delay: 1 sec to 99:59:59 (hrs:min:sec)
On Time: 1 sec to 99:59:59 (hrs:min:sec)
Stopwatch: Output turns on when started and off when stopped
Open Collector Outputs
Rating: Two NPN, Isolated open collector, 30 VDC @ 150 mA max
Output Assignment: Pulse, Alarm, Timer, Stopwatch on/off, or Disable
Pulse Output Source: PV (PV1, PV2) or Test Frequency
Pulse Output Factor: 0.000001 to 999,999.9

Alarm Output Source: Assign to PV (PV1, PV2) or Digital Input
Solid State Relays
Rating: Resistive Load: 250 VAC/DC @ 1 A
Inductive Load: 75 VA @ 0.6 A, 250 VAC/DC max (Safe Area only)
Noise Suppression: Metal oxide varistors across outputs
Relay Assignment: Pump Alternation, Alarm, Timer, Stopwatch on/off, or
Disable
Alarm Output Source: Assign to PV (PV1, PV2) or Digital Input
Pump Alternation: Relays will alternate with each pump cycle and
alternation can be based on elapsed time. Pump alternation time can be
programed for: 0 to 999:59 (hrs:min)
Relay (Pump) Runtime: Meter will keep track of how long each relay
(pump) has operated and display this information
Relay (Pump) Cycles: Meter will keep track of how many times the relays
(pumps) have cycled and display this information
