Simultaneously source and read any combination of
process milliamp and voltage signals. Altek's Model 934
combines all the functionality of a milliamp and a
voltage calibrator! This dual function calibrator
continuously displays the output and input signals. The
top half of the display indicates the output setting
while the lower half of the display shows the signal
being measured.
Calibrate state of the art equipment such as smart
transmitters and indicators to 41/2 or more digits using
the Model 934. Full 5 digit resolution lets you check
any brand of process control equipment. Your
calibrations are correct with accuracy surpassing 0.02%
of reading.
Use the scaleable display to match the readings on the
Model 934 to that of the equipment being calibrated. For
example, if your 4 to 20 mA recorder scale is 0.0 to
300.0 gallons/hour you can set the 934 to display 0.0
for 4 mA and 300.0 for 20 mA. No more need to use your
calculator or "cheat sheet" to come up with the correct
milliamp values.
Six "AA" alkaline batteries provide more than 20 hours
sourcing 20 mA continuously . . . more than 3 months of
typical use. From the time the low battery indicator
first comes on you have hours of power remaining to get
you through a shift without interruption. The 934 comes
configured to automatically power down after 30 minutes
of inactivity to save battery life.
Calibrate loop converters and isolators by
simultaneously providing the input signal and measuring
the output of the converter or isolator. Internal
optoisolators withstand up to 500 VDC between the source
and read leads. Calibrate and checkout all your process
milliamp and voltage instruments with the "benchtop
accurate" Model 934.
Use at any point in your 4 to 20 milliamp loop. Source
milliamps directly into your receivers with loop loads
up to 1200 Ohms. Simulate 2-Wire Transmitters for
checkout of field wiring and total loop testing. Power
and measure 2-Wire or 4-Wire transmitters on the bench
before installation. Read Transmitter & Controller
outputs up to 52.00 mA. Display directly in milliamps,
percent of 4 to 20 mA, percent of DP Flow or engineering
units to match the scale of your process.
Calibrate and checkout all your DC Voltage
instrumentation. Source up to 999.90 millivolts to
simulate sensors and up to 20.000 Volts to check your
process signal inputs. Measure voltages from -99.990 to
+99.990 VDC to check your power supplies and the outputs
from any process voltage equipment. Calibrate any 1 to 5
Volt device in a live 4 to 20 milliamp loop without
disconnecting any wires. The Model 934 will
automatically source or sink 0 to >16 milliamps to clamp
the test voltage in all source ranges. Output impedance
is less than 0.2 Ohm to let you calibrate voltage
instruments in milliamp loops without removing the input
load resistors. |
