AMPTEC 601ES Explosive Safety Safety DMM –Startup Check Out Procedure

The first item to examine is to check the calibration sticker due date for the AMPTEC 601ES Explosive Safety DMM. If the due date is still valid and not expired, it Is ready to begin the safety check procedure. If the calibration due date is expired then contact your calibration laboratory or AMPTEC RESEARCH. A tamper resistant calibration sticker is usually located around the perimeter areato the AMPTEC 601ES DMM covering one of the calibration access screws.

“ ”.

the “POW ER ON” switch ~ (2) secondsfor power The 601ES automatically turns after (30) minutes of idle use to conserve battery power.

“OFF”

Step 1: Procedure for turning on the 601ES DMM – Using main operating power switch.

Step 2: Observe the 601ES DMM display after unit is “powered up”. There should be no low battery (“LO BAT”) indicator present in the LCD display. ( see red circle area below)

The “LO BAT” display means it istime to replace the unit’s “AA” batterries. ( shown without backlight)

Since no “LO BAT” is displayed means,it means the unit’s batterries are OK. ( display shown with backlight lit mode )

The 601ES DMM is capable of indicating : “A” for amperes, “V” for voltage, , “k” for Kilo, “Ω ” for ohms. When the display indicates “>>> OR” or Overrange mode – it means possible “open circuit connection” or a higher range selection is required.

Step 3: Place the unit in “2 wire” measurement mode to begin the self check. (make sure that the 2 wire / 4 wire switch is in the the “up” position).

2 sections of the AMPTEC 601ES DMM are used for this process.The FUNCTION/RANGE section and the on-board analog milliammeter.

Step 4: The next set of steps envolves checking (by viewing the analog milliammeter) each range and function to see that less than 0.005 A ( or 5 mA) is ever output from any FUNCTION or selected range, into the unit’s onboard analog milliammeter.

You should see the analog milliammeter needle deflect to to midscale or the 5 mA (verticle needle position is “OK” – the milliammeter scale is 0 to 10 mA fullscale). You should not see 5 ½ milliamperes, avoid paralax viewing error of the milliammeter by taking reading straight over the milliammeter - use one eye to view. ( 8 mA is the failsafe current level).
