PIE 235 Process Voltage Calibrator
4Pages

Process Voltage Calibrator Source & Read DC Voltages Calibrate recorders in live loops Source pH • Technician friendly operation Intuitive EZ-DIAL Double Click Menu makes it easier to setup than other calibrators. Turn on the backlight to easily see the display in dark areas of the plant. Connections diagrams are indicated on the display for each function along with a labeled connector panel on the top. • Calibrate with Confidence Accurate to ±0.02% of Reading + 0.01% Full Scale. Out of range or over current is indicated by an audible alarm, flashing display and the OVERLOAD LED will light. • Source three ranges of mV & V dc plus percent of 1 to 5 volts With the 235 you can check, calibrate and measure all your voltage, millivolt and pH signal instruments in your plant. Source -500.00 to 999.00 mV, 1.000 to 5.000 V, 0.0 to 100.0% of 1 to 5 V; 0.000 to 20.000 V. • Power your loops with over 1,000 Ohm loads The 20.000 V range has an extended span of up to 24.000 Volts giving you a portable source for powering your loops. • Read DC volts The 235 can measure from -500.00 to +999.00 mV, 0.000 to 5.100 V, 0.0 to 100.0 % of 1 to 5 V; 0 to 20.000 V and 0.00 to 60.00 V DC. Use it to check loop power supplies, I/V converters, 1 to 5 Volt signals, and other voltages. Actual Size • Save time calibrating recorders and monitors in 4 to 20 mA loops Other brands of calibrators require that you break the loop to calibrate voltage inputs. With the PIE 235 you simply clip the test leads across the voltage inputs in a live 4 to 20 mA loop without disconnecting any wires. • Simulate pH probes into transmitters & analyzers Use the pH simulator to verify proper operation of pH devices before you place a probe into a calibrated buffer. • Quickly set any three outputs plus automatic stepping & ramping Easily set any value with the adjustable “DIAL” plus store any three output settings for instant recall with the EZ-CHECK™ switch. 2, 3, 5 & 11 steps automatically increment output in 100%, 50%, 25% or 10% of span plus continuous ramp. Set step/ramp time to 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 & 60 seconds. • Designed for you by experienced calibrator manufacturers PIE Calibrators are designed and built by members of the same team that designed and built the calibrators manufactured by Fluke* under the Altek* label. The 235 improves upon other brands by including a rubber boot, backlit display with larger digits, higher accuracy and more ranges for flexibility. * PIE Calibrators are not manufactured or distributed by Fluke Corp or Altek Industries Inc, manufacturers of Altek Calibrators.
