FEATURES

Except where noted all specifications apply to operation at +25ºC

INPUTS
Field selectable: 0-30 mV, 0-200 mV, ±15 mV, ±100 mV

RATIOMETRIC
Deviation less than 0.1% of full scale, ± 1 count, with ±10% variation in excitation voltage.

DISPLAY
Bright, large, 0.56" (14.2 mm) high efficiency red or green LED. 4½ digits + extra zero may be switched on to display ±19,999(0). Leading zeros blanked.

CALIBRATION RANGE
0 mV input may be set anywhere in range of the meter. 200 mV may be set anywhere above or below 0 mV input.

ISOLATED POWER SUPPLY
Selectable 5 VDC or 10 VDC ± 5% @ 50 mA or 24 VDC ± 5% @ 20 mA.     
Use to power either strain gauge or 4-20 mA output signal, (maximum load resistance of 1200 W).

PEAK HOLD
Captures peak reading and displays it via the front panel ENTER button.

PEAK HOLD INDICATION
Front panel LED

TARE
Captures/sets current display to zero via front panel TARE button.
Programmable tare: automatically sets tare to a preset value.

TARE INDICATION
Front panel LED

ACCURACY
0.05% of full scale, ± 1 count

NON-VOLATILE MEMORY
All programming values are stored in non-volatile memory for ten years if power is lost.

ZERO STABILITY
0.5 µV/°C

SPAN STABILITY
0.005% of full scale /°C

LOCKOUT
Switch 8 at rear of instrument restricts modification of programmed values.

INPUT IMPEDANCE
20 kilohms

POWER
115 VAC or 230 VAC ±10%, 50/60 Hz, 10 VA

ISOLATION
AC power: 1500 VAC
DC power: 500 VDC

ENVIRONMENTAL:
Operational Ambient Temperature Range: 0 to 60°C
Storage temperature range: -40 to 85°C
Relative humidity: 0 to 90% non-condensing

ALARM POINTS
4, any combination of high or low alarms

ALARM STATUS INDICATION
Front panel LED

ALARM DEADBAND
0-100% of full scale, user selectable

RELAYS

RATING
2 or 4 relays; SPDT (form C); rated 2 Amp @ 30 VDC or 2 Amp @ 250 VAC resistive load; 1/14 HP @ 125/250 VAC for NC contacts and 1/10 HP @ 125/250 VAC for NO contacts, inductive load.

FAIL-SAFE OPERATION
The relay coils are energized in the non-alarm condition. In the case of a power failure, the relays will go to the alarm state. May be disabled with internal jumper.

AUTO INITIALIZATION
When power is applied to the meter, the relays will always reflect the state of the input to the meter.

DEADBAND
0-100%, user selectable

CALIBRATION RANGE
The transmitter output can be calibrated so that a 4 mA output is produced for any number displayed on the meter. The 20 mA output may correspond to any number displayed on the meter that is at least 501 counts greater or smaller than the 4 mA output display. (Ex. 4 mA = 0, 20 mA = 501) If the span between 4 and 20 mA is less than 501 counts, an error message will appear.

ISOLATION
500 VDC or peak AC, input-to-output or input/output-to-power line

EXTERNAL LOOP POWER SUPPLY
35 V maximum

ENCLOSURE
1/8 DIN, high impact plastic, UL 94V-0

FRONT PANEL
Type 4X, NEMA 4X, panel gasket provided

CONNECTIONS
Removable screw terminal block, accepts 22 to 12 AWG
