Physical/Mechanical Parameters
Shunt Value
1 mA to 20 A
50 A and 100 A
Operating Environment
Temperature ....................................................... 13 ºC to 33 ºC
Calibration Temperature (TCal) Range............... 18 ºC to 28 ºC
Humidity Range for best specification
Altitude ................................................................ 0 m to 3,000 m
[1]
Resistance stability is affected by humidity, but changes are reversible.
[2]
If the shunts are calibrated outside this RH, stability specifications will be met as long as the shunts are stored and used at the
same relative humidity ±10% RH.
Storage and Transit Environments (for models other than the 1 mA Current Shunt)
Temperature to avoid damage............................ -20 ºC to 140 ºC
Temperature and Humidity to maintain
[1]
performance
................................................ 5 ºC to 45 ºC; 15% to 80 % RH
Non-operating Altitude ........................................ 0 m to 12,000 m
[1]
Storage at extremes of temperature or humidity will cause a temporary change of shunt resistance by up to ±20 ppm. When
subsequently stored or used within the limits of the operating environment, the shunts will recover to their original resistance value
within 30 days.
Additional 1 mA Current Shunt Specifications
Output Resistance ............................................. 8 mΩ
Maximum Safe Output Current .......................... 11 mA (e.g., 1 V output into 90 Ω )
Maximum Capacitive Load ................................ 800 pF
Output Voltage Regulation ................................. 15 ppm / 100 pF
Maximum Output DCV Offset ............................. ±100 μV (typical ± 25 μV)
Typical Error @ 1 MHz........................................ <2%
Battery Specifications
Battery Size ................................................... AAA (44.5 x 10.5 mm)
Battery Technology ......................................... Nickel-Metal Hydride (NiMH)
Number of Batteries Required ........................ 8 (in 2 groups of 4)
Nominal Battery Voltage ................................. 1.2 V (4.8 V per group of 4)
Typical Battery Capacity ................................. 800 mAh
Charging Time (from fully discharged) ........... 100 minutes
Maximum Operating Time Between Charges:
Maximum Output Load (11 mA) ................ 18 hours
High Impedance Load ............................... 24 hours
Recommended cooling period after
charging the batteries .................................... 100 minutes
Storage and Transit Environment to preserve the batteries
Less Than 90 days ..................................... -20 ºC to 40 ºC
Less Than 1 year ........................................ -20 ºC to 30 ºC
To prevent loss of battery capacity recharge at least twice per year.
