protection continues until the Instrument leads are disconnected (or until the
circuit fault is cleared).
The 260-6XPLM is not protected from catastrophic type overloads where the dam-
age due to overloads occurs within the response time of the protective relay, or
from voltages above the maximum capability of the Instrument.
1.4 Accessories and Supplies
All accessories and supplies required for the operation of the 260 is furnished with
each instrument, and listed in Table 1-2.
1.5 Technical Data
Table 1-1 lists the technical specifications for the Simpson 260-6XLPM Volt-Ohm-
Milliammeter.
NOTE: Accuracy specifications apply to measurements made with the Instrument
in a horizontal position (meter facing upward). Reference Conditions: +25°C ±5°C;
45% to 75% relative humidity.
Table 1-1. Technical Data
1. DC VOLTAGE
Ranges (full scale):
250 mV, 1.0V, 2.5V, 10V, 25V, 100V, 250V, 500V
and 1000V
Accuracy: ±2% of full scale on all ranges
Sensitivity: 20,000 /V
2. AC VOLTAGE
Ranges (full scale):
2.5V, 10V, 25V, 100V, 250V, 500V and 1000V
Accuracy: ±3% of full scale on all ranges
Sensitivity: 5000 /V
Frequency Response: See curve in Figure 4-1
3. OHMS CONVENTIONAL
Ranges:
RX1, RX100, RX1k and RX10k
Ohms Center: 6, 600, 6000 and 60k
Max. Scale Reading: 1000 (RX1)
Accuracy: ±2.5° of an arc on the RX1 range; ±2.0° of arc on
all other ranges. The nominal open-circuit volt-
age for all ranges up to RX1k is 1.5V. The RX10k
range has an open circuit voltage of 9V. The maxi-
mum current drawn from the 1.5V battery is 250
mA (RX1 with test leads shorted).
4. LOW POWER OHMS
Ranges:
RX1 and RX10
Ohms Center: 20 and 200
Max. Scale Reading: 1000 (RX1)
Accuracy: ±2.5° of arc. The maximum open circuit voltage
for the low power ohms ranges is 100 mV and the
maximum measuring power is 0.125 mW. The
battery quiescent current is 4.3 mA at RX1 and
0.43 mA at RX10.
