Refer to specific options described previously. 3.0 SAFETY CONSIDERATIONS This device is marked with the international caution symbol.
• Unit mounting should allow for adequate ventilation to ensure instrument does not exceed operating temperature rating. Use electrical wires with adequate size to handle mechanical strain and power requirements. Install without exposing bare wire outside the connector to minimize electrical shock hazards. EMC Considerations • Whenever EMC is an issue, always use shielded cables. • Never run signal and power wires in the same conduit. • Use signal wire connections with twisted-pair cables.
4 S /MAX BUTTON During run mode, pressing this button displays the “HI RDG” (peak reading) value that has occurred up to the moment the ‘MAX’ button is pressed. This peak reading flashes, to distinguish its value from the current readings. Since this is a dynamic peak reading, the value will change if the value increases while reviewing it. To return to display of the current readings without resetting the peak-value memory to zero (0), press the ‘MAX’ button once again.

Older RS-485 Option Board and Pin Designations 15.2 Front-Panel Pushbutton Configuration Setup configuration can be accomplished via the front panel buttons or via your computer if you use the configuration setup program. If you are going to use a computer, your choices include “AUTO SET” or “MANUAL SET” for establishing communication with your meter.
16.1 Tare (PIN 1) Tare is available when pin P2-1 and P2-4 are connected to a momentary contact switch. This feature allows you to automatically zero your meter when the switch is activated. 16.2 Peak (PIN 2) When this is connected to P2-4 by an external switch, the meter displays the stored PEAK (“HI RDG”) value rather than the current reading. The display flashes to distinguish this value. 16.
16.11 Print Command And/Or Reset Of Alarms (PIN 11) Grounding this pin to P2-7 when “BUS.8=1” has been programmed will initiate a meter printout via serial communications in the format previously selected. If “ALC.8=1” it causes the alarm latches to reset. 16.12 Nonstandard RX (PIN 12) And Nonstandard TX (PIN 13) These two pins allow digital communications with the meter using 5 V CMOS logic levels and RS-232 protocols and format.
17.1 Error Mode Messages 17.1.1 Flashing 999999 (Numerical Overflow) The maximum number of counts in the display cannot exceed –99999 or 999999. If, by moving the ACTIVE decimal point one or more places to the left, you cause the display to move beyond the maximum number of counts it is capable of showing (for example, 12345.0 to 12345.00), the display will indicate the overflow by flashing “999999”. 17.1.
17.2 Troubleshooting Guide 99999 POSSIBLE CAUSE: Active decimal point change driving the display into numerical overload. TO CORRECT: Press the ‘MAX’ button to reset the entire display to all zeros, then enter a revised number into the submenu item that caused the overflow. ERR 01 POSSIBLE CAUSE: Active decimal (“RDG.2=0”) has been selected and/or DEC PT (decimal point) position has been moved one or more places to the left driving the programmed offset value into numerical overflow.
TO CORRECT: Reduce the “CNT BY” count by value to 001. If you have an active decimal point selected, move the decimal point one or more positions to the right. UOM.OVF POSSIBLE CAUSE: Selection of unit of measure displayed (“RDG.6=0”) moves the display reading one place to the left causing a numerical overflow. TO CORRECT: If you have an active decimal point, move he decimal point position one or more positions to the right.
