Model 1062 Environment Monitor - DISCONTINUED

Model 1062 Environment Monitor

Continuously Monitors Environment

  • Temperature
  • Humidity
  • Barometric Pressure
  • Line Voltage
  • Line Frequency



The 1062A Environment Monitor will ensure that your ATE system's operating environment is properly controlled. The 1062A continuously monitors temperature, humidity, barometric pressure, line voltage, and line frequency. Up to 12 independent sensors plus the optional barometric pressure sensor can be connected to the 1062A. The sensors can be placed hundreds, even thousands, of feet away from the 1062A. The 1062A's compact half rack size, 3.5 inches high and 8.25 inches wide, makes it easy to rack mount directly into your ATE system rack thus freeing up table top and bench space.

Calibration Labs

The 1062A Environment Monitor and its sensors are traceable to the U.S. National Institute of Standards and Technology. Providing both high accuracy measurements and full GPIB and RS-232C programmability, the 1062A eliminates the need for chart recording and maintaining cumbersome paper records. Environmental data can be transferred directly to your calibration systems reports and Statistical Process Control programs. The 1062A provides you with the ability to correlate test failures or measurement perturbations with changes in environmental conditions, all in a "Paperless Calibration" environment.

Computer, Control and Clean Rooms

The large display and full function keyboard make the 1062A easy to read from a distance and easy to operate. Continuously monitoring the operating environment of sensitive electronic equipment, the 1062A will display the time at which the upper and lower extremes were measured for each channel. The 1062A supports the other 4 mA to 20 mA loop-powered or self-powered sensors for measuring many different parameters such as pH, conductivity, flow, position, level, current, dc voltage, tension, pneumatic and differential pressure, RPMs, and temperature (both RTDs and Thermocouples). Each channel's display can be customized for your specific application.


14 Channels with Flexible Displays

The 1062A offers 12 independently selectable 4 mA to 20 mA input channels, plus an AC line voltage/frequency monitoring channel and a dedicated channel for the optional Barometric Pressure sensor. Each channel's parameters can be independently set including: display title, display units, number of digits displayed, input and output scaling factors, alarm limits, and alarms activated. For your convenience, all parameters and settings are preset at the factory in both English and metric units.

Limits, Alarms, Min.Max Readings

Every 200 milliseconds all 14 channels are individually sampled, measured, converted to display units and compared against selectable alarm conditions and previous minimum and maximum readings. Any or all of the alarm indications can be activated including: audible alert, visual display, rear panel contact closure (or contact open), and computer SRQ interrupt over the GPIB interface.

Built-in Real Time Clock

The built-in real time clock provides you both current time and time-of-event information. The time-of-event data for each channel's minimum and maximum reading is stored in memory for later recall.

Calibration, Diagnostics and Special Functions

The 1062A is simple to calibrate. Only one manual adjustment is ever required - adjusting the time base frequency. All other adjustments can be made from the front panel keyboard or remotely over the GPIB or RS-232C. To insure proper operation the 1062A performs an extensive diagnostic check of its internal circuitry when first turned on. The 1062A offers many special functions including: number of measurements averaged per reading, RS-232C setup, audible alarm sound level, internal battery voltage, and metric or English default units.

Rear-Panel Recorder Output

The 1062A's user selectable recorder output lets you perform external signal processing of any of the 14 input channels. The recorder output's scaling factor is individually settable for each channel.



16 character alphanumeric vacuum-fluorescent display (VFD).

Mode Selection

Channel 1 to 12, time, line voltage, line frequency, barometric pressure, recorder and setup.

Setup Parameters

Upper limit (20 mA), lower limit (4 mA), alarm parameters (upper limit, lower limit, on/off for both limits and error condition), title (up to 10 ASCII characters), number of decimal places displayed to the right of the decimal point (0, 1, or 2), mA/V "raw" display, recorder upper/lower limits, special measurement modes, and min/max values.

Setup Presets

English and metric units for default parameters. Preset settings for each channel: option 01/03 temperature, option 01 humidity, or undefined.

Min-Max Function

Tracks minimum and maximum values and time-of-event for each channel 1 to12, plus line voltage, frequency, and barometric pressure. Min-max is reset using "START" function.

Real-Time Clock

Quartz-crystal real-time clock with battery backup. Time may be set from the front panel or via remote programming interface.


Activated by error conditions (open, overload, etc.) on any channel. Also activated by out-of-limits conditions on any channel. Alarm limits may be different than the channel upper/lower limits. All alarm conditions may be selectively disabled. Selectable alarm indications include: visual display, audible alert (with variable volume adjustment), contact closure (NO or NC), and computer SRQ interrupt.


GPIB (IEEE-488.2) and RS-232C (300 baud to 19200 Baud).

Chart Recorder Output

Plot any channel's instantaneous value, scaled between limits of your choice, on any standard chart recorder. Output is ± 5 Vdc.
