7 Displa y Functions The insturment operates in an y of sev eral modes which determine what infor - mation is visible in th e lo w er alphanumeric portion of the disp lay . The MODE button sequences through the menu functions. This b utton can be pressed re - peatedly until a desired mode is set.
Each of these operating mod es is described in the sections that follo w . 7.1 Blank Mode This mode is identified by “Blank” that temporarily app ears on the display .
In this mode nothing appears on the alphanumeric porti on of the display . Use this mode if you are only interested in the latest measurements and want to sim - plify the appearance of the display . The message “Prb cal expired”, “M tr cal expired”, “ Recharge Needed”, or “Probe is locked” may be displayed.
The labels can be pre-loaded using the W indo ws® HyperT erminal or o ther se - rial communications program and the command LBnn[=nnnnnnnn] as de - scribed in Section 8.
7.4.1 Clear A utolog? This function clears t he memory of all autologged dat a. Once the 1522 has logged 10,000 readings, further automati c logging is pre vented until the mem - ory has been cleared. Pressing the CLR button cancels the “Clr Autolog?” function and adv ances to the ne x t function.
Press the ENT butt on to stop autologgi ng and to adv ance to the ne xt function. 7.4.5 Dump Data? This function allo ws the user to download t he autologged data using the seri al port or print the do wnloaded dats to a serial printer .
button stores the selection. If th e MODE b utton or CLR button is pressed with - out pressing ENT the unit remains unchanged. Once the unit is select ed, subse - quent measurements will appear in that unit. After the Min/ Max and Delta(x) modes are initiated, their values are automatically con verted when changing units between °C, K, °F , or R.
When editing any parameter , be sure to press the ENT b utton through the enti re line of alphanumeric characters to ensure that the edi ts are stored. Pressing any button other than the ENT button adv ances to the next function wit hout storing the new v alue.

pressed, the message “In valid Passcode” i s displayed and the instrument is re - turned to the display mod e that follows the function that was acti ve when the CAL Mode was ent ered. Each indi vidual instrument has its o w n unique passcode. The passcode number is gi ve n on a notice pro vided with this i nstrument.
7.9.8 Prb T ype This function specif ies the type of probe an d its characterization. It allows the instrument to use the appropriate al gorithm to calculate te mperature from the measured resistance of the probe.

8 Comm unications Interface Remote communications allows an e x ternal de vice, such as a computer, to com - municate with the i nstrument to obtain measurement data and control its opera - tion. Communication is accomplished with v arious commands issued to the instrument through the RS-232 serial port.
The protocol for serial communicatio ns is 8 data bits, 1 stop bit, and no parity . Use no flow contr ol. The baud rate is f ixed at 2400, the linefeed to ON (all car - riage returns are follo wed by a linefeed (ASCII decimal 10)), and the duple x to HALF disabling ech o.
