OM-550 u 20 u 3.2 PAPER INS TALLATION 1. Unwind several inches of paper from the paper roll. 2. Fold the end of the thermal paper over creating a straight flat edge as shown in Figure 3- 2 . This creates a strong edge and allows the paper properly center in the printer when inserting it into the rear paper slot.
OM-550 u 21 u 3.3 D ATA PORT CONNECTION Prior to transferring data, the OM-550 must be connected to a PC with the RS-232 cable assembly supplied with the kit.
OM-550 u 22 u 4.0 PROGRAMMING When prior to operating the OM-550 it must first be programmed. This section covers all of the programming options available. All programmed settings but the time & date are stored in EEPROM and retained even if the batteries are removed.
OM-550 u 23 u 4.1 PROGRAMMING KEYS Pressing the PROG key activates the Program mode. The unit immediately prints the current programming information and prompts the user to select a channel to reprogram: Figure 4- 1 Channels may be defined as Voltage, Temperature (T/C) or Skipped.
OM-550 u 24 u 4.2 PRINT FORM ATTING When a Voltage channel (or the Math) channel is programmed, the OM-550 prompts the user for a decimal point position (or decimal point fix). This number between 0 and 5 is the location of the decimal point in the print field.
OM-550 u 25 u 4.3 TEMPER ATURE CHANNELS Any of the five channels can be programmed as Temperature channels. The user may select one of the four standard thermocouple types: J, K, T, or E and three optional types: B, S, or R. The Thermocouple types can be mixed.
OM-550 u 26 u 4.5 M ATH PSEUDO-CHANNEL The OM-550 has five physical channels and a sixth "channel" that can display the result of a math operation involving any two of the other channels (or a single channel, twice). The channels chosen as a basis for the Math channel are its "constituents".
OM-550 u 27 u 4.6 LOG INTERVAL The each active channel is scanned once during each log interval. The Log Interval is the time between readings, expressed in HH:MM:SS (hours:minutes:seconds). It can be programmed from one second to one day (00:00:01 to 23:59:59).
OM-550 u 28 u 4.7 OPER ATION AT FULL CACHE (RECORDING TIME) The OM-550 includes a battery-backed, 28-Kb data cache. The cache is erased when the RUN or PROG keys are pressed and new data is stored during logging.
OM-550 u 29 u 4.8 D ATE The current date is entered during programming and is kept in a real-time clock that is backed by the AA batteries. The clock will then be accurate unless the batteries are removed or a Manual Reset is executed.
OM-550 u 30 u 4.12 CALIBR ATION MODE The OM-550 includes a Cold-Junction Compensation network server that is automatically disabled during temperature calibration. Calibration mode temperature measurements performed in the usual manner will appear abnormal with the OM-550 in the CAL mode.
OM-550 u 31 u 4.13 TADJUST Tadjust is a cumulative value set during programming and summed with each Temperature channel's data during logging. It is cleared to a value of +00.
OM-550 u 32 u 4.14 VO LTAGE INPUT SCALING Any of the input channels (1 through 5) may be programmed as Voltage channels. Each Voltage channel includes unique m and b constants for "scaling" data to your application. These constants default to +1.
OM-550 u 33 u 4.14.3 MATCHING A CURRENT TRANSDUCER Use one resistor to develop the necessary voltage at the input: R1 V OM-550 INPUT I TRANSDUCER OUTPUT + - Figure 4- 9 V = OM-550 maximum input voltage = 2.
OM-550 u 34 u 4.14.4 DATA SCALING (mX + b calculation) The output voltage of a properly matched transducer can be read the but the data will be in "volts" and the user might prefer data in units that reflect the application. Programming the OM-550 to produce data in terms of the actual parameter being measured is called Scaling.
OM-550 u 35 u 4.14.5 MATCHING AND SCALING A VOLTAGE TRANSDUCER EXAMPLE: Given a 20 - 90 % RH (Relative Humidity) transducer with a 0 - 10 VDC output at a maximum current of 3 mA. Program the OM-550 to indicate 20.00 %RH to 90.00 %RH (that is, to indicate %RH with 0.
OM-550 u 36 u 3. Next, find m & b: X1 = 0 VDC ç minimum expected input = 0 A/D counts at Transducer minimum output X2 = 2.0000 VDC ç maximum allowable input = 20000 A/D counts at Tra nsducer maximum output Y1 = 20.00 %RH ç choose decimal point = 2 = 2000 display counts Y2 = 90.
OM-550 u 37 u 4.14.6 MATCHING AND SCALING A CURRENT TRANSDUCER Example: Given a 0 - 150-PSI transducer with a 4-20 mA output. Program the OM-550 to indicate 0 - 150 PSI with 0.01-PSI resolution. If the 4-20 mA Current Probe is being used, begin with step 2, below.
